WebHere, we are given the diameter of the sphere, 12.6 cm, which is twice its radius. To apply the formula to work out the surface area, we first need to calculate the radius, so we halve the diameter to get 𝑟 = 1 2. 6 ÷ 2 = 6. 3. Then, substituting for 𝑟 in the formula, we have 𝐴 = 4 × 𝜋 … WebSep 27, 2014 · hemisphere: circumference of great circle § 26 cm 62/87,21 We know that the circumference of a great circle is .

WebNote that the radius is simply half the diameter. The formula for the volume of a cylinder is: V = Π x r^2 x h. "Volume equals pi times radius squared times height." Now you can solve for the radius: V = Π x r^2 x h <-- Divide both sides by Π x h to get: V / (Π x h) = r^2 <-- Square root both sides to get: WebIt consists of a hemisphere on top of a cylindrical tube.
