Question

# The circumference of a circle is 123.2 cm. Calculate (i) the radius of the circle in cm. (ii) the area of the circle, correct to nearest cm^{2}

Hint:

### Circumference of the circle = 123.2 cm

## The correct answer is: 1207.36 cm2

### It is given that Circumference of the circle = 123.2 cm

(i). Circumference of the circle = 2 r

123.2 = 2 × × r

19.6 = r

(ii) Area of circle = r^{2}

= × (19.6)^{2}

= 1207.36 cm^{2}
