Let the original volume be pi *r^2* h where r = radius and h = height.
The new volume will be pi *(2/5 r)^2 * 4h = pi*4/25 r^2 4h
pi*4/25r^2 * 4h / pi r^2 h = 4/25 * 4 = 16/25
The volume has been reduced by factor of 16/25.
7(r-5)-3=r+34
7r-35-3=r+34
7r-32=r+34
7r-r=34+32
6r=4
6r divide by 6= 4 out if 6
Reduce it to its simplest form so 4 divide by 2 and 6 divide by 2 and your answer will be 2 out of 3
Hope this helps!!!
