To determine

To find the circumference of the circle, rounded to the nearest tenth.

Answer to Problem 10PPS

  $50.3$ inches

Explanation of Solution

Given information:

Radius(r) $=8$ inches.

Formula used:

Circumference (c) of a circle can be calculated using formula $2\times \pi \times r$

For calculations, value of $\pi =\frac{22}{7}$ .

Calculation:

  $c=2\times \pi \times r$

Formula to calculate the circumference of a circle.

  $=2\times \frac{22}{7}\times 8$

Putting the vale of the radius in the expression and simplifying.

  $=50.27$

Rounding off the number to the nearest tenth.

  $=50.3$ inches.
