Answer:
782.5inch³
Step-by-step explanation:
The question is on volume of a prism and that of a cylinder
Finding the volume of the prism
V=Bh where B is the base area and h is the height
Base area=14"×14"=196 inch²
height =8"
v=196×8= 1568 in³
Finding volume of the cylinder
v=r²h where r is the radius of cylinder and h is the height of cylinder
r=10/2=5 inches and h=10 inches
v=3.142×5×5×10=785.5inch³
The difference in volume
Difference in volume=1568-785.5=782.5in
Since there are 14 boys and the whole class has 31 students
We get, the ratio of the part-to-whole relationship for boys is 14/31.
And since there are 17 girls
We get, the ratio of the part-to-whole relationship for girls is 17/31.
