Find the surface area for a sphere with a radius of 7 cm. Round to the nearest whole number.
(1 point)
A 307c * m ^ 2
B 1, 436c * m ^ 2
C 1.02c * m ^ 2
D 615c * m ^ 2
The surface area of a sphere is given by the formula: 4πr^2
Given that the radius is 7 cm, we can substitute the value of r into the formula:
Surface area = 4π(7)^2
Surface area = 4π(49)
Surface area = 196π ≈ 615 cm^2
Therefore, the correct answer is D) 615cm^2.
