What angle does an arc 5.5cm in length subtend at the centre of a circle of diameter 7cm
1 answer:
Answer:
Below.
Step-by-step explanation:
7cm
(r) = 3.5cm
l = 5.5cm
Arc length = (Ѳ/360)2∏r
5.5 = (Ѳ/360)2*3.14*3.5
5.5 = (Ѳ/360)21.98
Divide 21.98.
5.5/21.98 = Ѳ/360
Ѳ/360 = 0.25
x 360.
Ѳ = 90
Arc angle is 90 degrees.
