2(pi)r = 9.4in
(pi)r = 4.7in
3.14r = 4.7in
r = 1.497in

Surface Area Of a Sphere = 4(pi)r^2 = [4(3.14)(1.497)^2]in^2 = 28.147in^2 = 28in^2
Volume Of a Sphere = 4/3(pi)r^3 = [4/3(3.14)(1.497)^3]in^3 =14.05in^3 = 14in^3

Answer:

47.25 ft³

Step-by-step explanation:

The volume of the prism is given by the formula ...

V = Bh . . . . . . . B is the area of the base, h is the height.

The height of the prism is given as 6 ft. The area of the base is the area of the triangular entrance. The formula for that area is ...

A = 1/2bh . . . . . . b is the base, h is the height

Using the given values for the entrance base and height, we get ...

A = 1/2(4.5 ft)(3.5 ft) = 7.875 ft²

Then the volume of the tent is ...

V = (7.875 ft²)(6 ft) = 47.25 ft³

The tent volume is 47.25 cubic feet.
