Hello!

To find the surface area of a sphere you use the equation

[tex]A = 4 \pi r^{2} [/tex]

A is surface area
r is radius

Put in the values you know and 3.14 for pi

[tex]A = 4 * 3.14 * 1.5^{2} [/tex]

Square the number

A = 4 * 3.14 * 2.25

Multiply

A = 28.26

The answer is D)28.26in squared

Hope this helps!
