The perimeter is 56.52 unitsStep-by-step explanation:
The The perimeter of a circle is π × d where d is the diameter
P = pi * d
since d is 18 so putting in the equation
P = 3.14 * 18
P = 56.52
and don't forget we all have different answers :D
it is B 89.95 in
i hope this helps you
Step-by-step explanation: Just had a test.
Hope this helps
Perimeter of a circle = 2πrSo, perimeter of a semicircle = πr/2 = πr
where π = 3.14 and r is the radius of semicircle.
diameter of semicircle = 35 inches
radius of semicircle will be half of its diameter = 35/2 = 17.5 inchesSolution
Perimeter of a semicircle = πr
= 3.14 (17.5)
= 54.95 inches
So, the best approximation for the perimeter of a semicircle with a diameter of 35 inches is 54.95 inches.
