Question

Find radius when area is 2464

Answer 1

$\huge{\underbrace{\sf{\purple{ Answer}}}}$

━━━━━━━━━━━━━━━━━━━━━━━━━━━

Area of circle = pi . r . r

Which can be written as

2464 = pi . r . r

Now,

2464 / pi = r . r

(2464 x 7) / 22 = r . r

784 = r . r

Solving for r (sq root of 784), we get r = 28 cms.

Hope I was able to explain it well.

Answer 2

Answer:

Area of circle:-

$\pi \: r {}^{2}$

$\frac{22}{7} \times r ^{2} = 2464$

$r {}^{2} = 2464 \times \frac{22}{7}$

$r {}^{2} = 352 \times 22$

$r {}^{2} = 16$

$r = \sqrt{16}$

$r = 4$
