If the perimeter of the semicircle is 10.28mm. What is the semicircles radius?

1 answer:

6 0

The formula for a circle’s circumference (circle’s unique perimeter) is pi * diameter.

However, since we have a semicircle (half of the circle), our formula would 1/2 * pi * diameter, or just pi * radius.

Set up an equation and solve.

10.28 = pi * radius.

r = (10.28)/pi

8_murik_8 [283]

Answer: (3, 13)

Step-by-step explanation:

If we let the point be P, then AP:BP=2:1.

$P=\left(\frac{(2)(3)+(1)(3)}{2+1}, \frac{(2)(19)+(1)(1)}{2+1} \right)=(3, 13)$
