Question

Find area of each figure. [Take π=3.14]
(a)A circle of Radius 16cm
(b)A semicircle of diameter 34cm
(c) A quarter circle of Radius 50cm ​

Answer 1

Step-by-step explanation:

(a) radius=16cm

area=πr^2

=3.14×16×16

=3.14×256

=803.84cm^2

(b) diameter=34 cm

radius=34/2=17cm

area=1/2πr^2

=1/2×3.14×17×17

=1.07×289

=309.23 cm^2

(c) radius=50cm

area of quarter circle= 1/4πr^2

=1/4×3.14×50×50

=1.07×25×50

=1.07×1250

=1337.50 cm^2

hope this helped u
