Question

find the radius and the circumference of a circle whose area is 144pi cm square​

Answer 1

Step-by-step explanation:

radius 12 cm

circumference 528/7 cm

Answer 2

Answer:

area =144πr^2

B.T.P

144π=πr^2

or,r^2=144

or,r=√144=12cm

thus,radius=12cm

circumference=2πr=2×(22/7)×12=24π=75.4cm
