RS Aggarwal Class 10 Solutions Areas of Circle, Sector and Segment
Question 1:
Radius = [latex]\frac { Diameter }{ 2 } =\frac { 35 }{ 2 } cm [/latex]
Circumference of circle = 2πr = [latex]\left( 2\times \frac { 22 }{ 7 } \times \frac { 35 }{ 2 } \right) cm [/latex] = 110 cm
∴ Area of circle = πr2 = [latex]\left( \frac { 22 }{ 7 } \times \frac { 35 }{ 2 } \times \frac { 35 }{ 2 } \right) [/latex] cm2
= 962.5 cm2
Question 2:
Circumference of circle = 2πr = 39.6 cm
