Answered by jaydons970

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
