What is surface square footage of 90' sphere?

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)

What is the surface area of 45 gallons?

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.

Suppose the sphere below with radius r has a surface area equal to 45 units 2 Find the surface area of the sphere with twice the radius'?

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.

If the volume is 60 what is the radius of a sphere in really simple terms for a Math dummy?

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
