Answer:

0.7m

Step-by-step explanation:

Given:

area of circle=1.54m^2

area of circle= pi(r)^2

pi=22/7=3.14

Solution:

22/7*r*r=1.54

r^2=1.54*7/22\\r^2=10.78/22

r^2=0.49

r=\sqrt0.49

r=0.7m

Given:

Area of circle = {1.54cm}^{2}

Area of circle formula = {πr}^{2}

π = \frac{22}{7} Or 3.14

Therefore,

\frac{22}{7} × r × r = 1.54

{r}^{2} = 1.54 × 7/22

{r}^{2} = \frac{10.78}{22}

{r}^{2} = 0.49

r = \sqrt{0.49}

r = 0.7m
