HELP! This is 8th grade math btw

1

Step-by-step explanation:

V= 1/3^r²h

V= (^r²h) ÷ 3

Cross multiply

3V = ^r²h

Divide both side by the coefficient of r²

3V ÷ (^h) = r²

Find the root of both side

r = square root of 3V ÷ (^h)

hi there!

step-by-step explanation:

a roof pitch is basically for every inch rise there is 12 inches run.

the height of the roof is also known as the rafter.

formula: rafter^2 = rise^2 + run^2

rafter^2 = 5^2 + 12^2

rafter^2 = 25 + 144

rafter ^2 = 169"^2

the height of the roof from the lowest point to the highest point is 169"^2.

hope this : )

step by step solution :

step   1   :

1.1     4 = 22

(4)3 = (22)3 = 26

equation at the end of step   1   :

  ((23) • 26)2

step   2   :

equation at the end of step   2   :

  (23 • 26)2

step   3   :

final result :

  218
