A sphere is increased to a bigger sphere such that its volume is increased by 27% find the change in surface areas
Answers
Answer:
Step-by-step explanation:
) A sphere is just enclosed inside a cube of volume 48 cm3
. Find the volume of the sphere.
(2) A sphere is just enclosed inside a right circular cylinder. If total surf ace area of cylinder is 75
cm2
, f ind surf ace area of sphere.
(3) If the radius of a hemisphere is 4r, f ind its total surf ace area.
(4) If radius of a sphere is 3b, f ind its surf ace area.
(5) The radius of a cylinder is halved and the height is tripled. What is the area of the curved
surf ace when compared to the same area previously?
(6) A sphere and a right circular cylinder have the same radius. If the volume of the sphere is f ive
times the volume of the cylinder, then what is the ratio of cylinder's height and radius?
(7) Find the volume the biggest hemisphere which can f it in a cube of side 4r.
(8) If a cylinder and hemisphere stands on equal bases, and have the same height. Find the ratio of
their volumes.
(9) If radius of a hemisphere is 4x, f ind its volume.
(10) A sphere is just enclosed inside a right circular cylinder. If volume of the sphere is 380 cm3
, f ind
volume o
