Radius of a circle is 10 cm. Measure of an are fo the circle is `54^@`. Find the area of the sector associated with the arc. (`pi=3.14`)

Text Solution

Verified by Experts

The correct Answer is:
`47.10 cm^2`
The radius of a circle ( r) = 10 cm
Measure of an arc of the circle (`theta`) = `54^@`
Area fo the sector `= theta/360 xx pir^2`
`=54/360xx3.14 xx10 xx10`
`=3xx1.57xx10`
`= 47. 10 cm^2`
