Question

Find the circumference of the circle. Round to the nearest tenth.

A. 148.4 m

B. 169.6 m

C. 84.8 m

D. 54.0 m

Answer 1

C. 84.8 m

Explanation:

Circumference of circle = D x 3.14

D = 27 m

Let's solve

27 x 3.14 = 84.78 m

So, the circumference of the circle is C. 84.8 m

Answer 2

Option C) 84.8 is the correct answer.

Explanation:

Here we have given that the diameter of circle is 27 m and we have to find the circumference of circle. The formula to find circumference of circle is :

`\dashrightarrow\sf{C = \pi d}`

Where :

• C = circumference
• π = 3.14
• d = diameter

Thus, finding the circumference of circle by substituting the given values in the formula :

`\dashrightarrow\sf{C = \pi d}`

`\dashrightarrow\sf{C = \pi * d}`

`\dashrightarrow\sf{C = 3.14 * 27}`

`\dashrightarrow\sf{C = 84.78 \: m}`

`\dashrightarrow\sf{C \approx 84.8\: m}`

Hence, the circumference of circle is 84.8 m.
