Question

A sumo wrestling ring is circular and has a circumference of 4.6pi meters what is the area a of sumo wrestling ring square meters?

Answer 1

Hey dear,

● Answer-
16.61 sq.m

● Explanation-
# Given-
C = 4.6π
A = ?

# Solution-
We know circumference of sumo wrestling ring is,
C = 2πr
4.6π = 2πr
r = 2.3

Area of sumo wrestling camp is given by,
A = πr^2
A = 3.14 × (2.3)^2
A = 16.61 sq.m

Area of the sumo wrestling ring is 16.61 sq.m

Hope this is useful...

Answer 2

Answer:Area of sumo wrestling ring is 16.63 square meters.

Solution:

We know that Circumference/Perimeter of circle
$= 2\pi \: r \\ \\ r = radius$
It is given that perimeter is 4.6π meters

$2\pi \: r = 4.6 \: \pi \\ \\ 2r = 4.6 \\ \\ r = 2.3 \: meter$
Area of circular ring
$= \pi \: {r}^{2} \\ \\ = \frac{22}{7} \times 2.3 \times 2.3 \\ \\ = \frac{116.38}{7} \\ \\ = 16.63 \: {m}^{2}$
Area of sumo wrestling ring is 16.63 square meters.
