Question

What is the surface area of a sphere with a diameter of 16 cm?

A. 1,024n cm²

B. 32n cm²

C. 256n cm²

D. 128n cm²

Answer 1

C is the correct answer

Answer 2

Answer:

The correct option is C. The surface area of a sphere is 256π cm².

Step-by-step explanation:

Given information: The diameter of the circle is 16 cm.

$r=\frac{d}{2}=\frac{16}{2}=8$

Radius of the circle is 8 cm.

Surface area of a sphere is

$A=4\pi r^2$

Where, r is radius.

$A=4\pi (8)^2$

$A=4\pi (64)$

$A=256\pi$

The surface area of a sphere is 256π cm². Therefore the correct option is C.
