Answer:
803.84
Explanation:
The Surface Area of a sphere can be solved by using the following equation:
A (Area of a sphere) = 4πr²
We know that r = 8 yards (Given), and that π ≈ 3.14 (Given). Plug in the corresponding numbers to the corresponding variables (& terms):
A (Area of a sphere) ≈ 4 * 3.14 * (8²)
Remember to follow PEMDAS. First, solve for the parenthesis:
(8²) = (8 * 8) = 64
Next, multiply across:
A (Area of a sphere) ≈ 4 * 3.14 * 64
A (Area of a sphere) ≈ (4 * 3.14) * 64
A (Area of a sphere) ≈ (12.56) * 64
A (Area of a sphere) ≈ 803.84
803.84 is your answer.*
*Note: The Surface Area of the sphere would be a little more if using a calculator, as it accounts for more decimals in the π. The difference can be ~0.41.
