Given,
circumference of the semicircle is 21.98 cm
To find,
The diameter of the semicircle.
Solution,
We can easily solve this mathematical problem by using the following mathematical process.
Let, the radius of the semicircle = r cm
Circumference of the semicircle = πr cm
(3πr is the perimeter of a semicircle, not it's circumference)
According to the data mentioned in the question,
πr = 21.98
22/7 × r = 21.98
r = 21.98×7/22
r = 6.99
Diameter of the semicircle = 6.99×2 = 13.98 cm
Hence, the diameter of the semicircle is 13.98 cm
