Question

Need help with these two questions.. WILL GIVE MEDAL

Answer 1

volume of the triangular prism = area of the triangle x the height ( 6 ft)

volume of the cylinder = area of the circle x height (42 ft)

do u know how to find the area of a triangle and a circle ?

Answer 2

triangle: a = 1/2 bh
circle: pi*r^2

everytime i do this, i get it wrong

Answer 3

area of the triangle
= 1/2 b x h
= 1/2 x 5 x 7 = 35/2
now multiply it by the height , which is 6ft to get the volume of prism
35/2 x 6 = 35 x 3 = 105 cubic ft

area of a circle
= pi*r^2
= 3.14 x (diameter/2)^2
= 3.14 x 8^2
= 3.14 x 64
= 200.96

now to get the volume multiply it by the height (42 ft)
= 200.96 x 42
= 8440.32 cubic ft

got it :) ?

Answer 4

Kind of.... it says to round my answer to the nearest cubic foot.... 8440?

Answer 5

yep!
