Question

Find the circumference and area of a circle of radius 17.5 CM

Answer 1

$circumferece \: of \: the \: cicle \: is \: 2\pi \: r \: = 2 \times \pi \times 17.5 \\ = 35\pi = 110m$

Answer 2

radius of circle =17.5cm.
circumference of circle=2πr
=2×22/7×175/10
=220cm

area of circle=πr^2
=22/7×175×175/100
=962.5cm^2
