Reference Information: Use the following formulas as needed.
Right circular cone: If r = radius and h = height, then
and if c = circumference of the base and ℓ = slant height, then
Sphere: If r = radius, then
and Surface Area = 4πr^2.
Pyramid: If B = area of the base and h = height, then
1 . A right circular cone and a sphere have equal volumes. If the cone has radius x and height
2 x, what is the radius of the sphere?
