The area formula is πr². Since, we are given the diameter we need to find the radius by dividing the diameter by 2.

radius = 20/2 = 10

Area = π(10)²
Area = 100π

The area of the pipe is 100π square units in term of pi.

Hope this helps :)

The butcher sold 63.8 pounds of meat on Monday. He sold 25.3 pounds more than that on Tuesday. On Wednesday, he sold 14.5 pounds
Elena-2011 [213]
Monday: 63.8
Tuesday: 63.8 + 25.3 = 89.1
Wednesday: 89.1 + 14.5 = 103.6

63.8 + 89.1 + 103.6 = 256.5

The butcher sold 256.5 pounds of meat over the three days.

Simplify.<br> -3(w+ 3) + 4w
densk [106]

Hello! :)

To solve you equation, we will first Distribute

(-3) (w) + (-3) (3) + 4w

= -3w + -9 +4w

Now, we will combine like terms

-3w + -9 + 4w

= (-3w + 4w) + (-9)

= w + 9

Hope this helped you!

Naily [24]
(8+2x) -> If 8 is added to twice a number (x)
5*(8+2x) -> and this sum is multiplied by 5
5*(8+2x)=x*(-28)+2   -><span>the result is the same as if the number is multiplied by negative −28 and 2 is added to the product.

Simplifying the equations on both sides would give
40+10x=-28x+2 transpose -28 to the left side and 40 to the right side
28x+10x=2-40
38x=-38
x=-1</span>
