1.

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

Answer»

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

$circumfernce = 2\pi \: r$

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