The area of a circle is PiR^2.
Since we know the radius, 1, we can square it and then multiply it by Pi.
Your answer is 3.14, since 1^2 is 1, and 3.14 x 1 = 3.14

Box D and Box E are made from unit cubes of the same size.
Dominik [7]

Answer:

Box E has a greater volume than Box D.

Step-by-step explanation:

Step 1 : Find the volume of Box D.

The formula for volume of a rectangular prism such as this is

height * width * depth

Knowing this, let's substitute the values.

3 * 5 * 1 = 15

The volume of box d is 15 cubic units.

Step 2 : Find the volume of Box E.

height * width * depth

4 * 4 * 1 = 16

The volume of box e is 16 cubic units. Therefore box E has a greater volume than box D.

Use the compound interest formula to compute the total amount accumulated and the interest eamed.
RideAnS [48]

Answer:

$12,137.39

Step-by-step explanation:

Use the Compound Amount formula:

A = P (1 + r/n)^(nt), where r is the interest rate as a decimal fraction, n is the number of times the interest is compounded each year, and t is the number of years.

Here, A = $9000(1 + 0.075/12)^(12*4), or

             =  $9000(1.3486) = $12,137.39

If B is the midpoint of AC, solve for x, and find the lengths of AB, BC, and AC.
makvit [3.9K]

Answer:

49, 49 , 98

Step-by-step explanation:

AC = AB + BC = 2AB

  • 3x - 31 = 2(x+6)
  • 3x - 31 = 2x + 12
  • 3x - 2x = 12 +31
  • x = 43

AB= BC = x + 6 = 43 + 6 = 49

AC = 2AB = 2* 49 = 98
