Best Answer

You can divide this problem into two steps:

1) Divide the circumference by (2 x pi) to get the radius.

2) Use this radius in the standard formula for the surface area of the sphere.

The surface area of a cylinder with a radius of 6cm and a height of 9cm is 565.5 units2

56.549 cm

It is 28.3 cm, approx.

Doubling the radius doubles the circumference.

The area of a rectangle of sides 9cm and 10cm is:9cm x 10cm = 90cm2This is equivalent to 0.009m2

Doubling the radius doubles the circumference.

The area of a rectangle of sides 9cm and 10cm is:9cm x 10cm = 90cm2This is equivalent to 0.009m2

The equation for circumference is C = 2*pi*r, where r is the radius of the circle and pi is a constant = 3.14159... Assuming that you mean a 9cm radius, the circumference is therefore: C = 2*pi*r = 2*pi*9cm = 18cm*pi = ~56.549cm

Surface area = (2*pi*32) + (pi*6*9)) = 72*pi which is about 226 square cm
