I need help on finding the height of a triangular pyramid

1 answer:

Mashcka [7]3 years ago

7 0

Answer:

20 in

Step-by-step explanation:

The formula for the volume of a triangular pyramid is V=1/3 x B x H, in which B is the area of the base and H is the height. You're given the volume and area of the base so you can just plug that into the formula. You will get 120 = 1/3 x 18 x H. You can multiply the 1/3 and 18 so you will get 120 = 6H. In this case, you are solving for H so you need to isolate the variable. You can do this by dividing both sides by 6. You will end up eith 20 = H.

What is the area of sector GPHthe area of the sector GPH is __ square yards. in exact terms of pi

finlep [7]

The Solution:

Given:

We are required to find the area of the sector GPH.

The formula for the area of sector GPH is:

$\begin{gathered} A=\frac{\theta}{360}\times\pi r^2 \\ \\ \text{ In this case,} \\ \theta=40^o \\ r=radius=15yards \\ A=area=? \end{gathered}$

Substitute these values in the formula.

$A=\frac{40}{360}\times\pi\times15^2=\frac{15^2\pi}{9}=25\pi\text{ }yards^2$

Therefore, the correct answer is:
