A20° sector in a circle has an area of 21.5π yd². what is the area of the circle? use 3.14 for pi. enter your answer as a decimal in the box.

The area of circle is 1215.18 yd²

Step-by-step explanation:

A 20° sector in a circle has an area of 21.5π yd²

Formula:

Where,

Area of sector = 21.5π yd²

Angle of sector = 20°

Now we will find the area of circle.

Hence, The area of circle is 1215.18 yd²

i got 142 as my answer

step-by-step explanation:

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
