Let
Haru's number ---> x
<span>Leon's number ---> (3/8)x
</span>so
ratio of
<span>Leon : Haru = (3/8)x : x </span>
<span>= 3/8 : 1 </span>
<span>= 3 : 8
</span>
the answer is
3 : 8
First you need the formula for SA of a cylinder: SA = 2(πr^2) + 2πr*h
(area of the top and bottom circles plus the side)
Then plug your values into the equation and rearrange to make h the subject:
1470.3 = 2π13^2 + 2π*13*h
26πh = 1470.3 - 338π
h = (1470.3 - 338π)/26π
=5.00042...
so h is approximately 5 units :)
