Respuesta :

the volume can be found with 
V= 1/3) Bh= 1/3 pi r² h 
r= 20/2 = 10
h = 17

V=  1/3 pi r² h = 1/3) *3.14* 10² *17= 1779 ft^3, so the answer is A. 1,780 ft^3

Answer:

The volume of teepee is 1,780 ft³

A is correct.

Step-by-step explanation:

Given: The diagram shows the dimensions of a teepee.

Diameter is 20 ft. Radius is half of diameter.

Teepee is shape of cone as per diagram.

Volume of cone [tex]=\dfrac{1}{3}\times \pi \times r^2\times h[/tex]

where,

r is radius of cone (r=10 ft)

h is height of cone (h=17 ft)

[tex]\text{Volume of teepee}=\dfrac{1}{3}\pi \cdot (10)^2\cdot 17[/tex]

[tex]\text{Volume of teepee}=\dfrac{1700\pi}{3}\approx 1780\text{ ft}^3[/tex]

Hence, The volume of teepee is 1,780 ft³
