Answer:
1715= 1/3 x 3.14 x r x r x 63
= 65.94 x r^2
÷65.94
26.01 = r^2
Square root
Radius is 5.1
1080 = 1/3 x 3.14 x 5.1^2 x h
1080 = 27.22 x h
÷27.22
39.67 = h
(Haven't been actually rounding up in my calculation, when I divided.)
Check:
1/3 x 5.1^2 x 39.67 x 3.14 = 1079.968146.
So, height is about 39.67cm
Hope this helps!
