A sphere has a radius of 2x +5. Which polynomial in standard form best describes the total surface area of the sphere? Use the f ormula S=4πr^2 for the surface area of a sphere.
1 answer:
Answer:
A
Step-by-step explanation:
Using the formula for the surface area with r = 2x + 5, then
S = 4πr²
= 4π(2x + 5)² ← expand the factor
= 4π( 4x² + 20x + 25) ← distribute parenthesis by 4π
= 16πx² + 80πx + 100π → A
