Given
( 1 ) To find the circumference of the circle :
( a ) Radius ( r ) = 21 cm
Circumference of circle = 2r
= 2 × × 21
= 132 cm
( b ) Radius ( r ) = 35 cm
Circumference of circle = 2r
= 2 × × 35
= 220 cm
( c ) Radius ( r ) = 63 cm
Circumference of circle = 2r
= 2 × × 63
= 396 cm
( d ) Radius ( r ) = 49 cm
Circumference of circle = 2r
= 2 × × 49
= 308 cm
( 2 ) To find the diameter of the circle :
( a ) Circumference = 77 cm
Circumference = × d
× d = 77
× d = 77
= 77 ×
= 24.5 cm
( b ) Circumference = 22 cm
Circumference = × d
× d = 22
× d = 22
= 22 ×
= 7 cm
( c ) Circumference = 121 cm
Circumference = × d
× d = 121
× d =121
= 121 ×
= 38.5 cm
( d ) Circumference = 66 cm
Circumference = × d
× d = 66
× d = 66
= 66 ×
= 21 cm
( 3 ) To find the circumference of the circle :
( a ) Diameter = 10 cm
Circumference = × d
= × 10
= 31.43 cm
( b ) Diameter = 7.7 cm
Circumference = × d
= × 7.7
= 24.2 cm
( c ) Diameter = 14 cm
Circumference = × d
= × 14
= 44 cm
( d ) Diameter = 63 cm
Circumference = × d
= × 63
= 198 cm
