Answer:
Perimeter : 103.5 cm
Step-by-step explanation:
12.5 will be the length for both sides of the quadrant (it's the radius) so 12.5*2 = 25
Now we have to find the length of the curve.
We can take the circumference of the circle and divide it by 4 (this is a quadrant, 1/4 of the circle)
Circumference of a circle equation; 2π r
In this equation 12.5 is the radius and we will use 3.14 as pi
12.5 * 2 * 3.14 = 78.5
25 + 78.5 = 103.5
