He raised $736.
One way is to multiply 640 x .15 = 96
Add 96 + 640 = 736
The square root of 64 is 8 but put 8 to the 1/2 power
The answer is 4
The tip here is to compute per solid. First the cylinder then the half sphere.
To get the volume of the cylinder we have:
V=πr^2<span>h where the r is 3 and h is 12. So the result is 339.29.
The volume of the sphere is V =(4/3)*</span><span>π*r^3 where the r is still 3. The answer then is 113.1.
The answer is then 144pi</span>
Approximately 9 meters are in 10 yards, (as there is approximately 1 meter in a yard, .9144 to be exact.)
There are 4 *parts* and 3 *parts*, a total of 7 parts each part must be 56/7 = 8
4 x 8 = 32
3 x 8 = 24
so its (that e looking thing) 32 and (that e looking thing again)24
