volume of cylinder = pi r2 h so if h = d, h = 2r so v= pi r2 2r depends on the lengths now just fill in the equation

2x plus 6y equals 32 32 divided by 6= 5 R2 5+2= 7x6= 42-5=37-2=35 so X=5

It's an incorrect statement. 5 plus 6 equals plus 11. Also, pi R round, cornbread R2 .

No, no it can't. Circumference = 2r*pi Area = pi*r2 For the area to equal the circumference pi*r2 = pi*2r so divide both sides by pi r2 = 2r so divide both sides by r r = 2 Note that circumference is in units and area is in units squared i.e. radius = 2m, area = 12.56637m2 Ciercumference = 12.56637 m

Surface area = 2*pi*r2 + 2*pi*r*h square units where r is the radius and h is the height. If height = diameter of the base, then h = 2r so that area = 2*pi*r2 + 2*pi*r*2r = 6*pi*r2

Area = pi*r2 = 2*pi*r = circumference then r2 = 2r so that r = 2

About 3.14159 of them. (pi) The area of a circle is (pi)r2. The area of the square into which the circle can be inscribed is 4r2 or (2r x 2r).

X2 + y2 = 100 = r2 r = 10

V = (pi)*R2*H if you double the radius then put 2R in place of R in the formula: V = (pi)*(2R)2*H V = 4pi*R2*H So the volume will increase 4 fold if you double the cylinder's radius.

The volume of a cylinder is equal to Pi times the square of the radius times the height of the cylinder. Pi*r2*h. Pi*r2 is the area of the base of a cylinder. The surface area of a cylinder is 2*Pi*r2+Pi*2r*h. 2*Pi*r2 is the area of the base of the cylinder times two to account for both bases. Pi*2r*h is the circumference of the base times the height of the cylinder
