Question

the circumference of a circle is 10 π find the radius and the area of the circle (take π = 3.14)

Answer 1

hello users ...

solution:-
we know that :
circumference of circle = 2πr
and
Area of circle = πr²

where,
r is the radius of circle.

here,
2πr = 10π
=> 2r = 10
=> r = 5

Now,
Area of circle = πr²
= 3.14× 5²
= 3.14 × 25
= 78.5 sq. unit Answer

Answer 2

circumfrence =2pi r
$2\pi \: r = 10\pi \\ r = 5 \\ area = \pi \: {r}^{2} \\ \: \: \: = 3.14 \times {5}^{2} \\ = 3.14 \times 25 = 78.5$
