To solve the equation 2*pi*r^2 + 2*pi*r*h you use the quadratic formula. r= [ -piáh ±?(pi_áh_+2áAápi)]/ (2ápi). You then get r>0 --> r= [ -piáh +?(pi_áh_+2áAápi)]/ (2ápi) .

How do you find the area of a cylinder?
The total surface area of a cylinder can be found using the formulaA = 2(pi)r2 + 2(pi)rh or A = 2(pi)(r2 + rh)2 (pi x radius squared) = both ends of the cylinderpi x (2 radius) x height = area along the cylinder's side (circumference x height)
What is the surface area of a cylinder whose radius is 11 inches and whose height is 11 inches?
There are two ends, each of area {pi}r2 and the side which can be worked out by cutting the cylinder down (from end to end) and unrolling; one length is the cylinder height (h), the other is the circumference of the end (2{pi}r), giving 2{pi}rh. Area = 2x({pi}r2) + 2{pi}rh Area ~= 2x3.14x112 + 2x3.14x11x11 Area ~= 1520.5in2
Surface area of a closed circular cylinder with 10 as the radious and 9 as the height?
The formula for surface area of a cylinder is: 2(pi)r2+2(pi)rh. r= radius h= height.
What is the area of a cylinder if the radius is 2cm and the height it 8cm?
Total Surface Area = 2Ï€r2 + 2Ï€rh = 2Ï€r(r + h) = 2Ï€*2(2 + 8) = 40Ï€ cm2 = 125.664 cm2 approx.
What is the formula of a cylinder by finding the surface area?
The area of a cylinder = 2πr2 + 2πrh, where π is pi (3.14159...), r is the radius of the top and bottom, and h is the height. Click on the related link below for a tutorial on how to find the area of a cylinder.

Can a child born with rh negative blood type be the offspring of an o positive father?
Yes, a child born with Rh negative blood type can be the offspring of an O positive father if the mother is also Rh negative, as the Rh factor is determined by both parents' blood types. If the mother is Rh positive, the child may inherit the Rh negative trait from the mother and be Rh negative.
Is the phenotype which determine RH?
The phenotype that determines the Rh factor in blood is based on the presence or absence of the specific protein antigens on the surface of red blood cells. A person can be either Rh positive (having the protein) or Rh negative (lacking the protein) based on their genetic inheritance.

If a father has O negative blood and the mother is a positive what would the child be?
Father is Rh-Rh-Positive blood type has two options so mother could be Rh+Rh+ or Rh+Rh- and so :Rh-Rh- X Rh+Rh+all kids will be positivethe second option isRh-Rh- X Rh+Rh-50% of the kids will be negativethe other 50% will be positive.
You have type O plus why does your father have O negative?
there is no problem with that, your Rh+ comes from your mother :) ur father genotype is Rh-Rh- your mother should be Rh+Rh+ or Rh+Rh- so you took one Rh- from your father and one Rh+ from your mother the result will be Rh+Rh- and because the +ve propriety is more dominant your blood type will be +ve even if you have the mix of Rh+Rh-
Monther is A positive and father is is B negative what make a child ab negative possible?
There are two genes that controll the traits. Since Rh+ is a dominant character, it could be expresssed even in the hterzygous condition. But Rh- could be expressed in the homozygous recessive conditions also. The father is Rh+ that means he could be either Rh+Rh+ or he could be Rh+Rh- and the mother is Rh-Rh-. The father should be Rh+Rh- type. So the gametes formed are of type Rh+and Rh-. When the Rh- gamete of male combine with the of Rh- female gamete the offspring is Rh-, with genotype Rh-Rh-.
When the Father type O negative and mother A positive what type of blood will the baby have?
The baby could have either blood type O positive or A positive. This is because the baby receives one blood type from each parent, and the A gene from the mother could combine with the O gene from the father to produce blood type A, or the baby could inherit the A gene from the mother and the Rh factor from the father to have blood type A positive.
If a Mother is A positive blood group and a Father is A positive blood group can they have a child that is O negative blood group?
That is always possible if both the parents are heterozygous for Rh antigen gene. It means that both the parents. There are 2 different alleles for the Rh factor known as Rh+ and Rh-.Someone who is "Rh positive" or "Rh+" has at least one Rh+ allele, but could have two. Their genotype could be either Rh+/Rh+ or Rh+/Rh-. Someone who Rh- has a genotype of Rh-/Rh-. If their genotypes are Rh+/Rh-, then their is possibility of of Rh- also.Rh factorPossible genotypesRh+Rh+/Rh+Rh+/Rh-Rh-Rh-/Rh-Prof. A.L. Bhatiahttp://www.competition-india.blogspot.com/http://www.albhatia.inType O blood is also recessive to type A, so both parents could be heterozygous type A's. Their genotypes would have to be A/O.
What is the formula for the base of a cylinder?
Surface are of a cylinder: 2(pi)r2 + 2(pi)rh Volume of a cylinder: 2(pi)r2h [pi = 3.14159..., r = radius of the cylinder's cross section, h = height of the cylinder]
Can a neg mother and b neg father produce a o neg?
the geno type for O- is ( ii Rh-Rh- ) the geno type for B- is ( IBIB Rh-Rh- ) or ( IBi Rh-Rh-) they can have a child with O type if the genes was (ii Rh-Rh-) and (IBi Rh-Rh-) in a 50%. but they can't have an (O+) because both parents are Rh(negative).
