Answer:
C = 8 pi cm
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
16 pi = pi r^2
Divide each side by pi
16 = r^2
Taking the square root
4 = r
The circumference is
C = 2 * pi *r
C = 2* pi *(4)
C = 8 pi cm
Answer:
divide the least common denominator by the original denominator
Hey!
RS = 15 and RT = 18. Subtract 18 from 15 to get your answer.

<em>That means your answer is 3</em>

18. 17.9
19. 21.1
20. I cant see the numbers sorry; if the sides are 6, √85 than it should have an angle of 40.6
The formula for finding the length is

All we have to do is plug in the numbers.

36 + 64 = 100
Since 100 =

we have to find the square root.

The length of the slide is 10 feet.
