Question

CALCULATE THE LENGTH OF AN ARC OF A CIRCLE OF RADIUS 14CM THAT SUBTENDS AN ANGLE OF 90 AT THE CENTRE

Answer 1

Answer:

Step-by-step explanation:

To find arc length, start by dividing the arc's central angle in degrees by 360. Then, multiply that number by the radius of the circle. Finally, multiply that number by 2 * pi to find the arc length.

OR

90/360 * (2 * pi * r)

Arc's Central Angle= 90 degrees

= 360/90= 4

= 4 * 14 cm=56

= 56 * (2 * pi)

= 56 * 6.28318530718

= 351.858377202
