which has a greatest volume a cube with side 15cm, a cone with radius 7cm and height 66 cm and a sphere with radius 21 cm?
Answers
Answer:
Volume of cube with side 15 cm = 15 x 15 x 15 = 3375 cm³
Volume of the cone = 1/3 x 22/7 x 7 x 7 x 66 = 3388 cm³
Volume of the sphere = 4/3 x 22/7 x 21 x 21 x 21 = 38808 cm³
Therefore, the sphere has the greatest volume with 38808 cm³.
Step-by-step explanation:
Since ,
Volume of a cube = side³
= 15³
= 3375 cm³
Volume of a cone = 1/3*π*radius ²*height
= (22*7*7*66)/(7*3)
= 3388 cm³
Volume of the Sphere =(4/3)*π*radius³
= (4*22*21*21*21)/(3*7)
=38808 cm3
Therefore, Volume of the Sphere is greatest.
