Answer:
Explanation:
To find the angle subtended by an arc of length 22/3 cm at the center of a circle with radius 7 cm, we can use the formula:
angle (in radians) = arc length / radius
First, we need to convert the arc length to radians by dividing it by the radius:
22/3 cm / 7 cm = 22/21 radians
Now we can convert radians to degrees by multiplying by 180/π:
angle (in degrees) = (22/21) x (180/π) ≈ 190.8 degrees
Therefore, the angle subtended by an arc of 22/3 cm at the center of a circle with radius 7 cm is approximately 190.8 degrees.
