Answer:
Step-by-step explanation:
1)
total area = rectangle area + 2 triangle area
= length * width = 2 ( * base * height )
= 7.5 * 6 + 2 ( * 3 * 4 )
= 57 ft²
2)
separate it into two rectangles:
length * width + length * width
6 * 2 + 9 * 4
48 cm²
3)
parallelogram area = base * height
= 20 * 25
= 500 in²
Answer:
inches or approximately 5.97 inches
Step-by-step explanation:
Use the cone volume formula: V = r²
The diameter is 8 inches, so the radius will be 4 inches.
Plug in the radius and volume, and solve for h
V = r²
100 = (4²)(
)
100 = 16
Divide each side by 16
=
Cross multiply and solve for h:
4h = 75
h =
So, the cone's height is or approximately 5.97 inches
