Surface Area of a Sphere Formula via Archimedes Approximation MethodPhaovibul, M Tip E
Cylinder: Say you have a cylinder with a radius = 3 cm and a height = 7 cm; its surface area would be calculated using the formula 2πr(h + r). It will be ( 2 × 3.14× 3 )(7 + 3) =188.4 cm². Sphere:For a sphere with r = 4 cm, the surface area would be calculate...
The surface area of a sphere is equal to ( 4) times Pi(π ) times the radius squared. ( 4π ⋅ ((radius))^2) Substitute the value of the radius( r=18) into the formula to find the surface area of the sphere. Pi(π ) is approximately equal to ( 3.14). ( 4⋅ π ⋅ ...
