What is the maximum area of a shape with a perimeter of 1000 m?
This might be a bit of a cheap answer, but: Of all shapes, circles have the highest area/perimeter ratio; that is, they have a maximum area for a minimum perimeter. 1000 = circumference = 2 pi r r = about 159.155 m area = pi (r squared) = about 79577.538 sq. m using pi = 3.14159
What is the sq ft of a 16x28 room?
16 x 28 sq ft...
What is square mm in cable size?

How do you calculate the louver vent size for return air required for an exhaust fan?
quick down and dirty way is the size of your unit (example..4 tons) X 144= the square inches needed for the return vent size or the longer way Max air flow from unit (rated size) / 2.08 cfm/sq in= filter area needed
How much surface will a yard of cement cover 3 inches thick?
Concrete is a mixture of cement , sand, gravel and water. A cubic yard of concrete is 3' x 3' x 3' . That's 3x3=9x3=27 . 27 cubic feet = 1 cubic yard . So it's 27 feet divided by 3 inches equals 108 sq ft!
What is x y sq over cos x pi?
Again, please clarify the question. Either "x=y^2/cos(x)*pi " or "x=y^2/cos(pi)". From the question it is not possible to tell whether the second "x" is a variable, or a multiplier sign (and if it were a multiplier, you're question is omitting a variable on the cos(x)).
Prove that sin theta power 8 - cos theta power 8 equal to sin sq Theta -cos sq x 1-sin sq Theta cos sq theta?
The equation cannot be proved because of the scattered parts.
What is cos 3 pie over 4?
- (sq rt 2)/2 approx. -0.7071
What is the exact value of cos 15?
It is: cos(15) = (sq rt of 6+sq rt of 2)/4
What is the area of a circle with a diameter that is equal to 12 inches to the nearest whole number?
36 pi: ie 36 x 355/113 = 113 sq in "and a little bit over"
What is the area of a basketball hoop if the radius is 14 cm?
a = pi r sq. a = pi 14 sq. or pi 196 a= pi X 196 if you leave in terms of pi
How do you find how many more square feet a 30 in circle is than a 18 in circle?
Area of 30 inch circle = pi*302 sq inches Area of 18 inch circle = pi*182 sq inches Difference = pi*(302 - 182) = 576*pi sq inches 1 sq foot = 1 ft*1 ft = 12 inches*12 inches = 144 sq inches so 576*pi sq inches = 576/144 *pi sq ft = 4*pi sq ft = 12.57 sq ft.
What is the surface area of a cylinder with a radius of 8 and a length of 14?
Surface area = 2*pi*r2+ 2*pi*r*h = 1105.8 sq units.=Surface area = 2*pi*r2+ 2*pi*r*h = 1105.8 sq units.=Surface area = 2*pi*r2+ 2*pi*r*h = 1105.8 sq units.=Surface area = 2*pi*r2+ 2*pi*r*h = 1105.8 sq units.=
What is Leonard Euler's famous formula?
eix = cos(x) + i*sin(x) where e is the irrational number 2.7182... i is the maginary sq root of -1 and x is measured in radians. In the special case when x = pi, this reduces to: eiπ = cos(π) + i*sin(π) or eiπ = -1
What is the diameter of a circle with an area equal to 616 sq in?
It is: 2*radius = square root of (616/pi) = 28 inches to the nearest integer
What is the circumference of a circle if its area is π?
If a circle has radius r, the area of the circle is pi X r2 and the circumference of the circle is 2 X pi X r. Therefore, the radius of the circle specified is (sq rt of n)/pi and the circumference is 2 X pi X [(sq rt of n)/pi]/pi = 2 X [(sq rt of n)/pi].
How many square meters are in a circle 2 meters in diameter?
Area = pi*(diameter/2)2 = pi*(2/2)2 = pi So pi sq metres = 3.14159 sq metres (to 5 dp)
