What is the volume of the cylinder with a radius of 8 and height of 4<br><br>​
mr Goodwill [35]

Answer:

Hey there!

The formula for cylinder volume is r^2h\pi, where r is the radius, h is the height, and \pi is a constant, roughly equal to 3.14.

Substituting all of these values into the equation:

8^2(4)(3.14)

804.84\\

Thus, the volume for the cylinder is 804.84 units cubed.

Hope this helps :)

James earned $39,600 last year. He paid $11,250 towards rent and $1,422 in car payments. What percent of his earnings did Jon pa
tester [92]
Step 1:
Add rent & car payments

=11,250+1422
=$12,672

Step 2:
to determine %, set up a proportion
12,672 is to his total of 39,600 as x is to 100

12,672/39,600 = x/100
cross multiply
(12,672)(100) = (39,600)(x)
1,267,200= 39,600x
divide both sides by 39,600
32%= x

OR

Alternative Step 2:
12,672 ÷ 39,600= 0.32
Alternative Step 3:
0.32 x 100 = 32%
or move decimal to the right 2 places

His rent and car payments are 32% of his earnings.

Hope this helps! :)
