Answer:
514.5 ft.³
Step-by-step explanation:
Volume of a triangular prism
= base area × height
In the figure, the base is a right-angled triangle.
The base area
= (7×7)÷2
= 24.5 ft²
The volume of the prism
= 24.5×21
= <u>514.5 ft³</u>
Answer:
<h2>d = 52 in</h2><h2>C = 6π mm²</h2>
Step-by-step explanation:
The formula of a circumference:

r - radius
d - diameter
We have
.
Calculate the diameter using
:
<em>divide both sides by π</em>

-------------------------------------------------------------------------
If a circle inscribed in a square, then the diameter of a circle and a side of a square are congruent (have the same length).
We have the area of the square:

The formula of an area of a square:

s - side
Substitute:

The formula of a circumference 
d - diameter
d = s → d = 6 mm
Substitute:

3/5 divided by 1/3 is 9/5 or 1 4/5
Therefore the answer is 1 and 4/5
