A balloon has a circumference of 28 in use the circumference to approximate the surface area of the ballon to the nearest square inch

Sagot :

The surface area of the balloon is 249 in².

What is the surface area of the balloon ?

A balloon has the shape of a sphere. The distance round the sphere is equal to the circumference of the sphere.

Circumference of the sphere = 2πr

Where:

  • r = radius
  • π = pi = 22 / 7

Radius - circumference / 2π

28 / ( 2 x 22/7) = 4.45 inches

Surface area of a sphere = 4πr²

4 x 22/7 x 4.45² = 249 in²
