Question

Please answer this question and give a step by step explanation and don't answer if you don't or I will just report. Thank you!! ​

Answer 1

Answer:

Given:

Circumference: Diameter = 22:7

Diameter = 2 m 1 dcm

To Calculate:

Circumference

Solution:

This question is related to Ratio and Proportion or Circle. Whatever.

We don't to find the radius. We can solve it in just a snap.

Diameter(d) = 2 m 1 dcm = 2.1 m

let, The circumference be x m.

According to question,

c/d = 22/7

c = d * 22/7

c = 2.1 * 22/7

27 21 22 C = x 10 7

3 * 22 10 C=

c = 66/10

c = 6.6

Therefore, The Length of circumference is 6.6 m.

Concept of T

What is π ? π is a irrational no. that can be expressed as the ratio of circumference and diameter of a circle. In terms of fraction it mainly used as 22/7 which a approximate value.
