The following answer is 10
Answer:
Correct answer: V = 82.5 in³
Step-by-step explanation:
This is a regular five sided prism.
Given:
The base edge a = 4 in
The radius of the inscribed circle or the height of an isosceles triangle
Ri = h = 2.75 in
Prism height H = 3 in
The base consists of five isosceles triangles
The area of one triangle is:
A₁ = a · h / 2
The area of the base is:
B = 5 · A₁ = 5 · a · h / 2
B = 5 · 4 · 2.75 / 2 = 27.5 in²
The volume of the prism is:
V = B · H = 27.5 · 3 = 82.5 in³
V = 82.5 in³

Answer:
Step-by-step explanation:
a^2+b^2=c^2
7^2+12^2=c^2
=193^2
find the square root of 193

Answer:
d = 4
Step-by-step explanation:
C = 2*pi r or C = pi * d
Area = pi *r^2= pi (d/2)^2 = pi * d^2 /4
So if they are numerically equal, you get
pi * d = pi * d^2 / 4 Divide both sides by pi
d = d^2 / 4 Multiply both sides by 4
4*d = d^2 Divide both sides by d
4 = d
