The diameter of a circle is 7 m. Find the circumference

to

to the nearest tenth.

Answer 1

22

Step-by-step explanation:

circumference equation = 2 x pi x radius

radius is half of diameter, so you do 7/2 which is 3.5 to get the radius. then with your calculator, you do 2 x pi(3.14) x 3.5 = 2.99.

then when you round 21.99 to the nearest 10, you get 22.

Answer 2

The diameter of the circle is 7 m, so we can substitute d = 7 into the formula:

C = πd

C = 3.14 x 7

C = 21.98

Rounding to the nearest tenth, we get:

C ≈ 22.0 m

Therefore, the circumference of the circle is approximately 22.0 meters.
