Ratio triangle height to square side 7:8
ratio triangle base to square side 1:2
Area of the square is 64 in² then the sides = 8 in

ratios give
h = 7(8)/8
h = 7

b = 8/2
b = 4

Area Triangle = 0.5(7)(4)
= 14

Then shaded region is the Area of the square minus the Area of the triangle.
A = 64 - 14
A = 50 in²

A cylindrical garbage can has a radius of 2.8ft and holds 86.21 cubic feet of trash. whats the height?
Crazy boy [7]

Answer:

Correct choice is A

Step-by-step explanation:

The volume of the cylinder can be calculated using formula

V=\pi r^2 h,

where r is the base circle radius  and h is the height of the cylinder.

In your case, V=86.21\ ft^3,\ \ \ r=2.8\ ft,

then

86.21=\pi\cdot (2.8)^2\cdot h,\\ \\h=\dfrac{86.21}{7.84\pi}\approx \dfrac{86.21}{7.84\cdot 3.14}\approx 3.5\ ft.
