The area of the semicircle is 14.13 square centimeters. Find the circumference of the semicircle

The area of the semicircle is 14.13 square centimeters. Find the circumference of the semicircle


The area of a semicircle multiplied by 2 is the area of the whole circle
With a calculator, 28.26 square centimeters
Divided by pi, squared, you get the radius
Radius times PI, plus the sum of the two radii, you get the answer
If the PI is 3.14, the answer is 15.42



It is known that the circumference of the semicircle is 25.7 meters. How about the area of the semicircle?


25.7 divided by 5.14 is diameter, diameter divided by 2 is radius, 3.14 times radius times radius



It is known that the circumference of a semicircle is 15.7 meters. Find the area of the semicircle


2πR=15.7*2=31.4
R=5
Semicircle area = π R2 / 2 = 3.14 * 25 / 2 = 39.25
