Question

The circumference of a circle exxeds its diameter by 135cm. Find the radius of the circle.

Answer 1

Diameter of Circle :-

= 135 cm

Diameter of Circle = Circumference of Circle

135 = 2 × $\bf\huge\frac{22}{7}$ × r

⇒ $\bf\huge\frac{135}{2}$ = 2 × 22 ×  $\bf\huge\frac{r}{7}$

= $\bf\huge\frac{2\times22\times2\times7}{135}$

Radius = 4 cm
