Question

if the area of the circle is 49πsq.units then its perimeter is​

Answer 1

Answer:

Area of circle=49π πr^2=49πr =√49r=7perimeter=2πr2×22/7×744 unitsplease

Answer 2

(｡◕‿◕｡)

Answer :

• Let radius of circle = r
• Area of circle = πr^2 = 49π inches^2

Note that π = 22 / 7

=> πr^2 = 49π

=> r^2 = 49π / π

=> r^2 = 49

=> r = √49 = 7

• So we need circumference of circle
• Circumference of circle = 2πr

=> 2πr = 2π ( 7 ) = 14π

=> 14 . 22 / 7

=> 2 . 22

=> 44 inches..
