Answer the following:Find the radius of the circle in which a central angle of `60^@` intercept an arc of length 37.4cm.(use pi=22/7)

Find the radius of the circle in which a central angle of 80^@ intercepts an arc of length 32.4cm.(use pi=22/7)

Answer the following:Find the centre and radius of the circle x=3-4sintheta and y=2-4costheta

Attempt the following : (1) Find the area of a circle with radius 7 cm.

Select and write the correct answer from the given alternatives in each of the following:The length of the arc of the circle which subtends an angle of 36^@ at the centre having radius 5cm is:

Solve the following:Find the area of a sector whose arc length is 30 pi cm and the angle of the sector is 40^@

Solve the following:Find the centre and radius of the circle passing through the points (2,0),(6,0) and (4,2).

In the adjoninog figure , radius of the circle is 7 cm and m (arc MBN) = 60^(@) find Area of the circle.

In the adjoining figure, the radius of the circle is 7 cm and m (arc MBN) = 60^@ . Find (i) Area of the circle

If the sector of a circle with radius 10 cm has central angle 18^(@) , find the area of the sector. (pi = 3. 14)
