Help plz i need sum quicc mathz

the answer is 1,055.04 ft^3

Step-by-step explanation:

you take 7 multiply it by 3.14 and multiply it by 4^2 the multiply the total by three.

A

Step-by-step explanation:

volume= πr²h.

3.14 x 4² x 7

3.14 x 16 x 7

= 351.68ft³

Since vol for each= 351.68, then for the 3 barrels it will be 351.68 x3

=1055.04ft³

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!

1. x> -5

2. x< 8

step-by-step explanation:

1. 2x> -10

divide by 2 from both sides of equation.

2x/2> -10/2

simplify, to find the answer.

-10/2=-5

x> -5 is the correct answer.

2. 3x< 24

divide by 3 from both sides of equation.

3x/3< 24/3

simplify, to find the answer.

24/3=8

x< 8 is the correct answer.

i hope this you, and have a wonderful day!
