Question

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

Answer 1

Circumference = 2*pi*R
R here = 17.5 cm

Therefore, Circumference =2*22/7*17.5
=770/7 =110 cm
Hope this helps!

Answer 2

Q. Find the circle's circumference and area of the circle of radius 17.5cm.

$\mathbb{ SOLUTION }$ :

Given : radius of the circle is 17.5 cm

To be found,
Circumference and area of the circle

Circumference of the circle = 2πr (in which $\bf{r}$ is the $\bf{radius}$ of the circle)

Circumference of the circle = 2 × $\frac{ 22}{ 7}$ × 17.5

$\therefore$ Circumference of the circle = 110cm

Now,

Area of the circle = πr² (in which $\bf{r}$ is the $\bf{radius}$ of the circle)

Area of the circle = $\frac{22}{7}$ × (17.5)²

Area of the circle = $\frac{22}{7}$ × 17.5 × 17.5

$\therefore$ Area of the circle = 962.5cm²
