Hey!

------------------------------------------------

Technically c has already been solved.

Lets, solve even further.

We know that pi is equal to 3.14

c = 2(3.14)r

c = 6.28r

This would be simplified.

------------------------------------------------

Hence, the answer is $\Large\boxed{\mathsf{c~=~6.28r}}$

------------------------------------------------

Hope This Helped! Good Luck!

How many 1/6 pieces are there in 3/6<br>

dmitriy555 [2]

Answer:

there are 3 1/6 pieces

Step-by-step explanation:

since 3 x 1/6=3/6.

another explanation:

(3/6)/(1/6)=(3/6) x (6/1) since you multiply by inverse when dividing fractions. Then, (3/6) x (6/1) = 18/6, which equals 3.

36 3⁄4 gallons of water come out of a hose in 15 minutes. Write the ratio in fractional form and determine the water rate in gal

Brrunno [24]

Answer:

Step-by-step explanation:

If 3⁄4 gallons of water come out of a hose in 15 minutes, to calculate the rate of water that comes out in an hour (60 minutes), we will use the expression;

3/4 gallons = 15 minutes

x gallons = 60minutes

cross multiply

15x = 3/4 * 60

15x = 180/4

15x = 45

x = 45/15

x = 3/1

x = 3:1

Hence the water rate in gallons per hour is 3 gallons per hour

Two angles in a triangle have measures of 25° and 55°.

rosijanka [135]

Answer:

B) 100

Step-by-step explanation:

All 3 interior angles of a triangle add up to 180 so:

x + 25 + 55 = 180

x + 80 = 180

x = 180 - 80

x = 100
