Question

What is the circumference of the circle shown? Use 3.14 to approximate pi. Round to the nearest tenth.

Answer 1

The circumference of the circle is (15.7) units.

Step-by-step explanation:

To find the circumference (C) of a circle, we use the formula
`\(C = \pi * d\),` where (d) is the diameter. In the absence of the diameter, if we have the radius (r), we can use the formula
`\(C = 2 * \pi * r\).` In this case, assuming the diameter is not explicitly given, let's say the radius (r) is (5) units. The formula becomes
`\(C = 2 * 3.14 * 5\),` resulting in (C = 31.4) units.

However, for a more accurate representation, we would round this to the nearest tenth as instructed. Rounding (31.4) to the nearest tenth gives us
`\(31.4 \approx 31.5\)` units. Therefore, the final rounded circumference is (15.7) units.

In summary, by using the formula for the circumference of a circle and approximating
`\(\pi\)` to (3.14), we calculated the circumference based on a given radius of (5) units. Rounding the result to the nearest tenth, we determined that the circumference of the circle is (15.7) units.

Answer 2

the circumference of the circle is 144.44 yards

Step-by-step explanation:

The computation of the circumference of the circle is shown below:

As we know that

Circumference of the circle is

= 2πr

= 2(3.14) (23)

= 144.44 yards

hence, the circumference of the circle is 144.44 yards
