A leather ball has a diameter of 28.4 cm. Which is the area of the piece of leather used on the surface of the ball?

Ira Lisetskai [31]

Answer:

$A=806.56\pi\ cm^2$

The diameter of a leather ball, d = 28.4 cm

Radius, r = 14.2 cm

We need to find the area of the piece of leather used on the surface of the ball. The surface area of the ball is given by :

$A=4\pi r^2\\\\A=4\times \pi\times (14.2)^2\\\\A=806.56\pi\ cm^2$

So, the area of the piece of leather is $806.56\pi\ cm^2$ . The correct option is (b).
