HELP PLEASE :) What is the circumference of the circle shown below

B. 66.0

Step-by-step explanation:

Circumference of a Circle Formula: C = 2πr

We are given r = 10.5, so simply plug it in:

C = 2π(10.5)

C = 21π

C = 65.9734

or

C ≈ 66

B. 66.0

Step-by-step explanation:

One of the radius measure 10.5 because the line is between the center point and the edge of the circle.

Circumference = 2πr

C = 2(3.14)(10.5)

C = 2(32.97)

C = 65.94 ≈ 66.0

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
