Find the area of the circle if its circumfence is 88 cm.
Answers
Answer:
The circle’s area is 616.47 sq.cm
Step-by-step explanation:
Given:
Circumference = 88 cm
Step-by-step explanation:
A circle is a closed surface such that the center of it is equidistant from all the points on the circle.
Circumference of a circle is the perimeter or length of the whole edge.
Circumference of a circle = 2Πr
Where,
r is the radius of the circle.
2 \pi r=882πr=88
r=\frac{88}{2 \pi}=\frac{44}{\pi}=\frac{44}{3.14}r=
2π
88
=
π
44
=
3.14
44
\therefore r=14.012 cm∴r=14.012cm
Area of the circle is the total value inside the circle’s circumference.
The formula for area of a circle = \pi r^2πr

Where,
r is the radius of the circle which is the length included from center towards any point on the circle.
\text{Area}=\pi \times 14.012 \times 14.012=3.14 \times 196.33Area=π×14.012×14.012=3.14×196.33
\Rightarrow \text { Area }=616.47 \ \mathrm{cm}^{2}⇒ Area =616.47 cm

Answer:-
The circle’s area is 616.47 sq.cm
Given:
Circumference = 88 cm
Step-by-step explanation:
A circle is a closed surface such that the center of it is equidistant from all the points on the circle.
Circumference of a circle is the perimeter or length of the whole edge.
Circumference of a circle = 2Πr
Where,
r is the radius of the circle.
=>2πr = 88
=> r =88/2π
=>r=44/π
=>r =44/3.14
=>r=14.012
Area of the circle is the total value inside the circle’s circumference.
The formula for area of a circle =
Where,
r is the radius of the circle which is the length included from center towards any point on the circle.
=>π×14.2×14.2
=>3.14×196.33
=>Area =616.47
