Question

the circumference of a circle is 17.6cm find the area of circle

Answer 1

HEY MATE

HERE IS YOUR ANSWER
$circumference \: of \: the \: circle \: \\ = 2\pi \: r \\ so \: 17.6 \: = 2\pi \: r \\ 17.6 \: = 2 \times 22 \div 7 \times r \\ r = 17.6 \times 7 \div 2 \times22 \\ r = 1355.2$
NOW
AREA OF CIRCLE IS =
$\pi \: r {}^{2}$
So
$22 \div 7 \times (133.5) {}^{2}$
=8518.4 ans

Hope it is correct

Answer 2

Answer:

Step-by-step explanation:

Circumference=2πr

17.6=2×22/7×r

176×7/10×2×22=r

r=88×7/10×22

r=4×7/10

r=28/10

r=2.8cm

Area=πr²

=22/7×(2.8) ²

=22/7×28/10×28/10

=11×2/5×28/5

=616/25

=24.64 cm²
