Question

8.) a round patio is 14m in diameter. What is the distance around the patio? A. 153.86m B. 21.98m C. 43.96m D. 615.44m

Answer 1

So by having a circle with a diameter of 14 metres it is a sake of calculating the circumference of the patio. This is simply done by (where d = 2r, d is the diameter, and r the radius)

$C = 2\pi r = 2\cdot \pi \cdot \left \frac{14}{2} \text{ m} \approx 43.98 \text{ m}$
