@eta

Answer 5

Wanna start it from somewhere?

Answer 6

Do we have options?

Answer 7

can you start

Answer 8

how do i start by setting it up @eta

Answer 9

Find AC length first..

Answer 10

I am not getting it actually but then also let us start..

Answer 11

to find ac is is a^2+b^2=c^2

Answer 12

I need to refresh on Properties of Right Pyramid..

Answer 13

we can do a different one right now if you want

Answer 14

Do we have options or answer choices?

Answer 15

nope

Answer 16

for the other one yes

Answer 17

Answer 18

Find AC, let us do it..

Answer 19

\[AC^2 = AB^2 + BC^2\]

Answer 20

12.04

Answer 21

No. we are doing wrong I think.

Answer 22

oh

Answer 23

A cone has a diameter of 30 in. and a slant height of 17 in.

What is the approximate volume of the cone? Use 3.14 to approximate the value of straight pi. Round your answer to the nearest tenth, if necessary. (Hint: V equals 1 third straight pi r squared h )



A.
7536.0 in3

B.
5345.9 in3

C.
2419.9 in3

D.
1884.0 in3

Answer 24

\[Volume = \frac{1}{3} \pi r^2 \cdot h\]

Answer 25

r is radius here, but you are given SN = 30, SN is diameter of that circle, can you find Radius first?

Answer 26

15

Answer 27

it says diameter is 30 so radius is 15

Answer 28

Good..
