V = 972pi cu.yds
V(sph) = (4/3) pi r^(3)
Hence
972pi cu.yds = (4/3) pi r^(3)
Cancel doewn by 'pi'
972 = 4r^(3) / 3
Multiply bo the sidex by '3'
Hence
2916 = 4r^(3)
Divide both sidesx by '4'
729 = r^(3)
Take the cube root of both sides
729^(1/3) = r
r = 9 yds.

Volume of a sphere = 4/3*pi*radius3 Volume = 4/3*pi*93 = 3053.628059 Volume = 3054 cubic feet to the nearest cubic foot.
The formula to calculate the surface area of a sphere is 4πr^2, where r is the radius of the sphere. Plugging in the radius of 7.5 meters into the formula, we get 4π(7.5)^2 = 4π(56.25) = 225π square meters. Therefore, the surface area of a sphere with a radius of 7.5 meters is 225π square meters, or approximately 706.86 square meters.
The volume of a cylinder is PI * R2 * H If H is the same as R, then it is PI * R3 (Or PI * H3)
pi*r2*6 = 678.24 Divide both sides by pi*6: r2 = 35.98174953 Square root both sides: radius = 5.998478935 cm
