A half-filled cylindrical water tank has a water level of 20 feet high. The tank can hold 6000 cubic feet of water. Find the dia

Anettt [7]

Answer:

d = 13.8 feet

Step-by-step explanation:

Because we are talking about cubic feet of water, we need the formula for the VOLUME of a cylinder. That formula is

$V=\pi r^2h$

We will use 3.141592654 for pi; if the tank HALF filled with water is at 20 feet, then the height of the tank is 40 feet, so h = 40; and the volume it can hold in total is 6000 cubic feet. Filling in then gives us:

$6000=(3.141592654)(r^2)(40)$

Simplify on the right to get

$6000=125.6637061r^2$

Divide both sides by 125.6637061 to get that

$r^2=47.74648294$

Taking the square root of both sides gives you

r = 6.90988299

But the diameter is twice the radius, so multiply that r value by 2 to get that the diameter to the nearest tenth of a foot is 13.8

A paperweight is shaped like a triangular pyramid. The base is an equilateral triangle. Find the surface area of the paperweight

stich3 [128]

Answer:

The surface area of the paperweight is $SA=8.3\ in^2$

Step-by-step explanation:

we know that

The surface area of the triangular prism is equal to the area of its triangular base plus the area of its three triangular lateral faces

Find the area of its triangular base

$SA=\frac{1}{2}(2)(1.7)$

$SA=1.7\ in^2$

Find the area of its three triangular lateral faces

$SA=3[\frac{1}{2}(2)(2.2)]$

$SA=6.6\ in^2$

Adds the areas

$SA=1.7+6.6$

$SA=8.3\ in^2$

Solve for C. Thank you to whoever answers!!!!!!!!!!!!!!!!!!!

faltersainse [42]

Answer:

c=7

Step-by-step explanation:

How to solve your problem

8=−3+29

8=−3c+298=-3c+298=−3c+29

Solve

Subtract

292929

from both sides of the equation

8=−3+29

8=−3c+298=-3c+298=−3c+29

8−29=−3+29−29

8−29=−3c+29−298{\color{#c92786}{-29}}=-3c+29{\color{#c92786}{-29}}8−29=−3c+29−29

Simplify

Divide both sides of the equation by the same term

Simplify

Solution

Hope this helps!

Have a great day!
