Type number only. No units. Do not round till the end. Round answer to the nearest tenth.

S.A. = ⁉️

Answer 1

Answer: 1017.4.

Explanation:

S.A. = 4π(9^2)

Calculating this:

S.A. = 4π(81)

= 324π

S.A. ≈ 1017.36

Rounded to the nearest tenth, the surface area of the sphere with a radius of 9m is approximately 1017.4.
