Question

find the radius and diameter of the circle given the area-55.44cm​

Answer 1

Answer:

are of circle = 55.44 cm2

π r^2. = 55.44

r^2. = 55.44 × 7/22

r^2 = 5.04 × 7/2

r^2 = 2.52 × 7

r^2 = 1764/100

r = 42/10

r = 4.2 cm

Hope you get it

thank you

Answer 2

Answer:

Radius of circle = 4.2

Step-by-step explanation:

Area of circle = 55.44cm

Area of circle = πr² cm²

=> 22 x r² = 55.44

7

=>r² = 55.44 x 7

22

=> r² = 17.64

=> r = √17.64

=> r = 4.2
