If the surface area of a sphere is 484π, what is the radius?
2 answers:
Answer:
It would be 11.
Step-by-step explanation:
The equation for the surface area of a sphere is 4πr^2, so lets reduce the answer to get the value of r, the radius.
484π = 4πr^2
Divide by π
484 = 4r^2
Divide by 4
121 = r^2
Lastly, square root each side
11 = r
r is 11.
Answer:
6.21 is the radius I believe
