Question

Please help me solve. the answer I have is incorrect.

Answer 1

196π yd²

1) Considering that sphere with the radius = 7 yds, we can find out the surface area using the following formula:

`A=4\cdot\pi\cdot r^2\Rightarrow A=\text{ 4}\pi(7)^2\Rightarrow A=\text{ 196}\pi yd^2`

Plugging into the formula, we can state that the answer is 196π yd² (approximately 615.75 yd² -rounded off to the nearest hundredth)
