First we have to find the radius:
4*pi*radius2 = 78.5 square yards
Divide both sides by 4*pi:
radius2 = 6.246831516
Square root both sides:
radius = 2.499366223 yards
Volume of a sphere = 4/3*pi*radius3
Volume = 65.40008284 cubic yards
First find the radius: 4*pi*radius2 = 25pi square yards Divide both sides by 4*pi: radius2 = 6.25 Square root both sides: radius = 2.5 Volume of the sphere = 4/3*pi*2.53 = 65.449 cubic yards to 3 d.p.
2,144.66 cubic yards.
Volume of a sphere = 4/3*pi*radius3 Volume = 3053.628059 or 3056 cubic yards to the nearest cubic yard
Volume: 4/3*pi*33 = 113.097 cubic yards to three decimal places.
Volume = 4/3*pi*73 = 1436.75504 cubic yards
First find the radius: 4*pi*radius2 = 25pi square yards Divide both sides by 4*pi: radius2 = 6.25 Square root both sides: radius = 2.5 Volume of the sphere = 4/3*pi*2.53 = 65.449 cubic yards to 3 d.p.
Surface = 9*pi yd2 Therefore radius = 1.5 yards and so volume = 4.5pi yd3 or 14.137 yd3
2,144.66 cubic yards.
Volume of a sphere = 4/3*pi*radius3 Volume = 3053.628059 or 3056 cubic yards to the nearest cubic yard
The volume of a 30-yard diameter sphere is 14,100 cubic yards.
523.6 cubic yards.
33.5 cubic yards (approx).
Volume: 4/3*pi*33 = 113.097 cubic yards to three decimal places.
25 yards2 ????If so....,Area sphere = 4*pi*r2You have area, so....,25 yrd2 = 4*pi*r2r = sqrt(25/4*pi)= 1.41 yards in radius-----------------------------Volume sphere = 4/3*pi*r3Volume = 4/3*pi(1.41 yrd)3= 12 cubic yards===============
Volume = 4/3*pi*73 = 1436.75504 cubic yards
The surface area of a sphere is (4 pi) x (radius of the sphere)-squared.We're not completely sure of what a "90' sphere" is. If you're saying that thesphere's diameter is 90-ft, then its radius is 45-ft, and its surface area is(4 pi) x (45-ft)-squared = 25,446.9 square feet, or 2,827.4 square yards. (both rounded)
Yes, I think I can.Here I go.Watch this :Volume of a sphere = 4/3 pi R3 = (4/3) (pi) (15)3 = 14,137.17 cubic yards (rounded)
