2 x pi x radius = circumfrance

2 x pi x radius = 29

29/ 2pi = radius

radius = 4.62 (3 sig.fig.)

4 x pi x radius^2 = Surface area of sphere

12.56 x radius^2 = Surface area of sphere

12.56 x 4.62^2 = Surface area of sphere

268 cm2 (3 sig.fig)

The circumference of a hollow ball is 19cmwhat is the surface area?

First find the radius by dividing 19 by 2*pi which is 3.023943919 cm Surface area of a sphere (the ball) = 4*pi*radius2 Surface area = 4*pi*3.0239439192 => 114.9098689 Surface area of the ball: 115 square centimeters correct to three significant figures.


Is circumference squared or cubed?

Circumference isn't squared OR cubed. However, Surface Area is squared and so is Area. So Circumference is just Circumference :)


What is the formula for finding the surface area of a hollow cylinder?

2 X Pi X radius X height = area Circumference X height = area (times two if you want inside and outside assuming the walls are of zero thickness)


How do you find the surface area of a cylinder when given the height and circumstance?

Entire surface area of a cylinder = (2*pi*radius^2)+(circumference*height) If you are given the circumference then radius = circumference/2*pi


What is the formula for finding the surface area of hollow cylinder?

The formula for finding the surface area of a hollow cylinder is: 2πrh + 2π(R+r)h, where r is the inner radius, R is the outer radius, and h is the height of the cylinder.


Does the diameter surface area and circumference affect the heat loss?

yes heat loss is affected by diameter, circumference and surface area. Heat loss depends on the surface area : volume ratio.......the larger this is the more heat is lost if a cylinder having the same volume but a different surface area...(therefre radius and circumference is different)........the cylinder having the larger surface area will loose heat fastest
