and a hemisphere of equal surface area each have a 3-inch radius. what is the height of the cone?
SA = pi*r^2 + pi*rl
Where,
r is the radius
h is the height
l is the slant height
given: ...........eq.1
surface area of a hemisphere SA = 3pi*r^2
given: ..........eq.2
from eq.1 and eq.2 we have
...divide by -> slant height
the height of the cone will be
