Answer:

18 cm

Step-by-step explanation:

The circumference (C) of a circle is calculated as

C = 2πr ← r is the radius

Given

C = 36π, then

2πr = 36π ( divide both sides by 2π )

r = \frac{36\pi }{2\pi } = 18

Explain in words what mistake you made and how will correct it. in a group of 20 children,there were 8 girls. which is the ratio
Nataly_w [17]
Well first do 20 children minus 8 girls to find how many boys there are:
20-8=16
So there are 16 boys. Therefore we can write the ratio of girls to boys as:
8/16
Then we can simplify this ratio by dividing it by 8 to get:
1/2
So the answer is the ratio of girls to boys in the group in simplest form is 1/2.

Fed [463]

Answer:

x = 12, y=7

x=30, y=25

x=15, y=10

Step-by-step explanation:

We have :  y = x - 5

x = 12  then y = 7,     y = 12 - 5 = 7

x = 30     25 = x - 5,   x = 25 + 5 = 30

x = 15,  y = 15 - 5 = 10,  y = 10
