What is the approximate area of the following circle?

balu736 [363]

Answer:

$38.47 {m}^{2}$

Step-by-step explanation:

The formula to find the area of a circle is

$a= \pi {r}^{2}$

We know that

$\pi = 3.14 \: \: \: \: \: \: r = 3.5$

Therefore the area is

$a= \pi {r}^{2} \\ \\ a = (3.14) {(3.5)}^{2} \\ \\ a = 3.14 \times 12.25 \\ \\ a = 38.47 {m}^{2}$

Cougar Park is shaped like a parallelogram and has an area of 1/10 square mile. It’s base is 3/8 mile. What is its height?

VikaD [51]

To find the missing dimension (the height) you can use the formula A=bh and substitute and let you know. 1/10=3/8h. To find the missing factor (h) you will divide both sides by 3/8. 1/10 divided by 3/8 is the same as 1/10 x 8/3. The answer is 4/15 mile. You show this has h=4/15 mi.

A 42-inch board is to be cut into three pieces so that the second piece is twice as long as the first piece and the third piece

Karo-lina-s [1.5K]

Answer: 7 inches

Step-by-step explanation:

If x is the first piece, and the second piece is twice as long, then the second piece is 2x.

If the third piece is three times as long as the first piece, x, then the third piece is 3x.

The 42-inch board must be equal to all 3 pieces, so we will set up an equation and solve for x.

42 = x + 2x + 3x

42 = 6x

7 = x

The first piece is 7 inches long.
