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)

The surface area depends upon the shape of the volume of 45 gallons. The minimum is a sphere: volume_sphere = ⁴/₃ × π × radius³ → radius = ∛(³/₄ × volume_sphere ÷ π) = (³/₄ × volume_sphere ÷ π)^⅓ surface_area = 4 × π × radius² → surface_area = 4 × π × (³/₄ × volume_sphere ÷ π)^⅔ 1 US gallon ≈ 0.161 cu ft → 45 US gallon ≈ 7.22 cu ft → minimum_surface_area ≈ 4 × π × (³/₄ × 7.22 cu ft ÷ π)^⅔ ≈ 18.07 sq ft. Therefore the surface area of 45 US gallons is greater than or equal to approx 18.07 sq ft. 1 imp gallon ≈ 0.00455 cu m → 45 imp gallon ≈ 0.205 cu m → minimum_surface_area ≈ 4 × π × (³/₄ × 0.203 m³ ÷ π)^⅔ ≈ 1.679 m² Therefore the surface area of 45 imperial gallons is greater than or equal to approx 1.679 m².
A circle with a radius of 45 units has a circumference of 282.74 units.
The area of a sphere is given by the formula A = 4πr² A sphere with radius r has an area = 4πr² A sphere with radius 2r has an area = 4π(2r)² = 4π.4r² = 16πr² The ratio of the larger sphere to the smaller = 16πr² : 4πr² = 4 : 1 If the area of the smaller sphere is 45 units then the area of the larger sphere is 45 x 4 = 180 units.

A sphere with a volume of 45 cubic units has a radius of 2.21 units. If you double the radius to 4.42 units, the volume becomes 362 units3Apex answer: 360 units3
381703.5074 inches cubed Volume=(4/3)*pi*radius cubed So Volume = (4/3)*pi*45^3=381703.5074
If radius = 45 mm, then area = 6361.7 mm2 (to 1 dp).
The area of a circle can be calculated using the formula A = πr^2, where r is the radius. Given a radius of 45 km, the area would be approximately 6,366 square kilometers.
The surface area depends upon the shape of the volume of 45 gallons. The minimum is a sphere: volume_sphere = ⁴/₃ × π × radius³ → radius = ∛(³/₄ × volume_sphere ÷ π) = (³/₄ × volume_sphere ÷ π)^⅓ surface_area = 4 × π × radius² → surface_area = 4 × π × (³/₄ × volume_sphere ÷ π)^⅔ 1 US gallon ≈ 0.161 cu ft → 45 US gallon ≈ 7.22 cu ft → minimum_surface_area ≈ 4 × π × (³/₄ × 7.22 cu ft ÷ π)^⅔ ≈ 18.07 sq ft.

If the radius of a sphere is r, then its volume is 4/3*pi*r3 So, 4/3*pi*r3 = 60 ie pi*r3 = 60*3/4 = 45 then r3 = 45/pi = 45/3.14 = 14.32 so r = cube root of 14.32 = 2.43
