Question

Area of a circle is 154 cm², then it's radius is​

Answer 1

Answer:

7.0031

Step-by-step explanation:

Area of a circle = π(r)^2  [ here π = 3.14 and r = radius]

putting the values we get:

3.14(r)^2 = 154

r^2 = 154/3.14

r^2 = 49.04

r = √49.04

r = 7.0031

Answer 2

Answer:

radius² = 154/pie

154×7/22

7×7

r² = 49

49squre root
