Question

Find the diameter of the cirlce whose area is 2826 m square

Answer 1

$\underline{\large\bf{\mathfrak{Hello!}}}$

According to the question the area of the circle is 2826 m²

$Area \: of \: circle = {\pi} {r}^{2} \\ \\ => 2826 = {\pi} {r}^{2} \\ \\ = > {r}^{2} = \frac{2826}{\pi} \\ \\ = > {r}^{2} = \frac{2826}{3.14} \\ \\ = > {r}^{2} = 900 \\ \\ => r = \sqrt{900} \\ \\ => r = 30$

So, radius of circle = 30 m

Therefore diameter of the circle will be = 30 × 2
= 60 m

$\boxed{Diameter \: of \: circle = 60 \: m}$

Answer 2

Area of circle = pi×r^2 = 2826 m^2
3.14×r^2 = 2826 m^2
r^2 = 2826÷3.14
r^2 = 900 m
r = root900
r = 30 m
D = 2r
D = 2×30
D = 60 m
