Question

Taking π = 3.14 find the radius and circumference of a circle whose area is 379.94sq.m​

Answer 1

Step-by-step explanation:

$area \: of \: circle = \pi {r}^{2}$

$379.94 = \pi {r}^{2}$

${r }^{2} = 379.94 \div 3.14 = 121$

$radius \: r = 11$m

$circumfernce = 2\pi \: r$

$circumference = 2 \times 3.14 \times 11 = 69.08m$

Answer 2

Step-by-step explanation:

area of circle =πr^2

379.94= 3.14*r^2

379.94/3.14=r^2

r^2=121.01

r=11.004m

circumference=2πr

=2*3.14*11.004

=69.105m
