Answer: 170
Step-by-step explanation:
Hemisphere volume formula
V = (2/3)πr3
(2/3)•(3.14)•(2.5)^3=32.7 (33)
Cylinder volume formula
V=πr^2h
(3.14)(2.5)^2(7)=137.4 (137)
137+33=170
Divide the whole (4 5/8 feet) by the size of the pieces (5/8 foot)
x= number of 5/8 foot pieces
x= 4 5/8 feet ÷ 5/8 foot pieces
*Multiply by 5/8 reciprocal (inverse)
*Change 4 5/8 to improper fraction
x= 37/8 * 8/5
x= (37*8) / (8*5)
x= 296/40
x= 7 4/10
*Simplify fraction
x= 7 2/5 or 7.4 pieces
There are 7 2/5 five-eighth foot sized pieces.
Hope this helps! :)
