Answers

Answer 1

Answer:

Answer:

B. 1,130.40 cubic feet

Step-by-step explanation:

Volume of a cylinder is

V = pi * r^2h

We know r=6 and h =10 and use 3.14 for pi

V = 3.14 * 6^2 *10

V =3.14*36*10

V = 1130.4 ft^3

Can someone please solve 10n - 3 = 7n + 21

Answers

$10 n-3 = 7n+21$

Add 3 to both sides :

$10n-3+3=7n+21+3$

$10n=7n+24$

Subtract 7 n from both sides:

$10n-7n=7n+24-7n$

$3n=24$

Divide both sides by 3 :

$(3n)/(3) = (24)/(3)$

$n = 8$
