Answer:
perimeter of circle is C=2πr
1) (a) half circle C=2πr/2
= πr
=3.14 X 10
= 31.4 cm
1) (b) 1/4 circle + 1/4 circle = half circle
= 2πr/2
= πr
= 22/7 X 7 in.
= 22 in.
2) (a) here two half circles are joint
= first has 10 in. + second has 5 in.
= 2πr/2 + 2πr/2
= πr + πr
= (3.14) (10) + (3.14) (5)
= 31.4 in. + 15.7 in
= 47.1 in
2) (b) the figure is not saw clearly...... retake it..
