Step-by-step explanation:
The volume of a cylinder is given by :
r is the radius of the base of a cylinder
h is height of cylinder
The height of a cylinder is twice the radius of its base. It means that h = 2r
So, volume of cylinder becomes :
So, the volume of the cylinder is given by the expression .
#46
(m-8n)(m + 4n)
#49
(h - 8j)(h +11j)
Divide both sides by 5 and then n + 2 =2 so the answer is n=0
hope this help
A= pi×r^2 r=(1/2)d
A=pi×(1/2)d×(1/2)d
A=pi×0.5d×0.5d
A=pi×(0.5)^2 × d^2
A=pi×0.25d^2
