Answer: The radius of the ball is 7 meters.
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Surface area of a sphere: 4 π r^2
Replacing with the value given:
615.75 = 4 π r^2
Solving for r (radius):
615.75 /4π= r^2
√(615.75 /4π) =r
r = 6.99 = 7m (rounded)
The radius of the ball is 7 meters.

Using the shell method, the volume is
Each cylindrical shell has radius (the horizontal distance from the axis of revolution to the curve ); has height (the vertical distance between a point on the -axis in and the curve ).
Compute the integral.
Maybe u add them up does it say area if so its multiply from it says a diff word I forgot it's subtract
