Wittaler [7]

Answer:

209.96

Step-by-step explanation:

we know that the circumference of the circle is equal to

C = $\pi D$

we have

$D = 64 ft$

substitute would be

$C = \pi (64) = 64\pi ft$

assume that $\pi = 3.14$

64 $64\pi = 64 * 3.14 = 200.96 ft$

The perimeter of a rectangle is 28 cm and<br>its length is 8 cm. Find its breadth.

Yakvenalex [24]

Answer:
The width of the rectangle is 6cm.

Explanation:
Perimeter=2(length+width)
28=2(8+w)
Distribute 2 into the parentheses
28=16+2w
Combine like terms
28-16=2w
12=2w
Divide both sides by 2
6=w

I hope this helps! Please comment if you have any questions.
