Question

the circumference of a circle exceeds its diameter by 135 cm find the radius of the circle

Answer 1

Hello,

Diameter Of Circle=135cm

Diameter Of A Circle=Circumference Of Circle
135=2πr
135÷2=2×22×r÷7
Radius=2×22×2×7÷135
Radius=4 Cm

Thus,The Length Of The Radius Is 4Cm.

Thank You,

Answer 2

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
