The perimeter of the semicircle is 19π cm if the diameter of the circle is 38 cm.
<h3>What is a circle?</h3>
It is described as a set of points, where each point is at the same distance from a fixed point (called the centre of a circle)
We have a circle with diameter of 38 cm.
Diameter = 38 cm
The radius of the circle = 38/2 = 19 cm
Perimeter of the circle = 2πr = 2π(19) = 38π cm
Perimeter of the semicircle = 38π/2 = 19π cm
Thus, the perimeter of the semicircle is 19π cm if the diameter of the circle is 38 cm.

36 in = 1 yard
1800 in = 1800/36 = 50 yards.
It’s B ) THE SLOPE IS POSITIVE
Sqare √113
113
10^2=100, so √100=10
11^2=121 so √121=11
√100<√113<√121
so therfor
10<√113<11
it is between 10 and 11
