The correct question is
<span>The radius of a cylinder is 5" and the lateral area is 70pi sq. in. Find the length of the altitude.
</span>
we know that
[surface lateral area]=(2*pi*r)*height
height= [surface lateral area]/(2*pi*r)
surface lateral area=70*pi in²
r=5 in
so
height= [70*pi]/(2*pi*5)------> 7 in
the answer is
7 in
Answer:
80
Step-by-step explanation:
Circle circumference = 2*pi*r
160*pi = 2*pi*r
(160*pi)/2*pi = (2*pi*r)/2*pi
80 = r
