Determine the circumference of a circle with a radius of 6.8. Round your answer to the nearest tenth.

A) 42.7 units
B) 21.4 units
C) 36.3 units
D) 145.3 units

Answer :

Answer:

The correct answer option is A) 42.7 units.

Step-by-step explanation:

We are given the radius of a circle to be 6.8 and we are supposed to find the circumference of this circle.

We know the formula for the circumference of a circle:

Circumference of a circle = 2πr

So substituting the given value of the radius of the circle in the above formula to get:

Circumference of the circle = 2 * π * 6.8 = 2 * 3.142 * 6.8 = 42.7

Therefore, the correct answer option is A) 42.7 units.

Answer:

A) 42.7 units

Step-by-step explanation:

Here we have to use formula to find the circumference of a circle.

Circumference of a circle = 2*π*r

The value of π = 3.14

Given: The radius of the circle = 6.8

Now plug in the given value and value of π in the formula.

The circumference of the circle = 2*3.14*6.8

C = 6.28*6.8

C = 42.7

Answer: A) 42.7 units

Thank you.
