Answer:
The answer is 96cm.
Step-by-step explanation:
Given data:
Length of shorter arc = 12 cm
A shorter arc subtends an angle of 45° at the center.
Now find the circumference of the circle by the following formula.
θ/360 x 2πr = length of the arc
Here θ is the angle, r is the radius and 2πr is the circumference of the circle.
45 /360 x 2πr = 12 cm
0.125 x circumference of the circle = 12
Circumference of the circle = 12 / 0.125
Circumference of the circle= 96 cm
