CAN SOMEONE PLEASE HELP ME WITH THIS GEOMETRY QUESTION THANK YOU !!!

Step-by-step explanation:

The construction of the figure gives us three right triangles, where we can apply Pythagora's Theorem.

I have added two variables to the image in the picture attached.

On the triangle with sides y,h,16 we have:

On the triangle with sides h,z,25 we have:

Equating :

On the bigger triangle with sides y,z,16+25=41 we have:

Adding this last equation with [1]:

Simplifying:

Operating:

Dividing by 2:

Taking square root:

y=20

To enter the number in the required format:

use formula for the circle a=3.14

step-by-step explanation:

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
