Answer:
1386cm squared
Step-by-step explanation: first find the diameter.
132=pi x diameter
132=22/7xd
multiply both sides by 22/7 and you'll get 42cm
then find the area by doing this.
22/7x21x21 which gives you 1386cm squared.
the 21 is the radius.

Answer:
The length of the arc is 1.0467
Step-by-step explanation:
First of all to solve this problem we need to use the circumferenc formula of a circle:
c = circumference
r = radius = 3
π = 3.14
c = 2π * r
we replace with the known values
c = 2 * 3.14 * 3
c = 18.84
The length of the circumference is 18.84
Now we have to divide the 20° by the 360° that a circle has, to know what part of the circle it represents
20° / 360° = 1/18
Now we multiply this fraction by the circumference and obtain the length of the arc
1/18 * 18.84 = 1.0467
The length of the arc is 1.0467
