the ratio of circumference of a circle to its diameter is 22:7. what is the circumference of a curcle of the diameter 15.6m?
Let the circumference be Y.
Then 22:7 = Y:6
22/7 = Y/15.6
Cross multiple
22 x 15.6 = 7 X Y
= 343.2 = 7Y
To get our Y we dive both sides by 7
343.2/7 = 7Y/7
= 49.0285
Y = 49.03
The circumference of the circle is 49.03 Ans
Follow the rules carefully......
c=15.6(22/7)=3.1428571
c=15.6*3.1428571=49.028571
Approximately becomes=49.03
C/15.6 = 22/7
=C = 15.6(22/7) = appr 49.03
C/15.6 of 22.7,c=15.6(22/7)=49.028 approximately=49.03
yea it's 49.03.
u guys are gud
Is correct
Thanks for the answer and it's correct
Correct answer
Thanks
To find the circumference of a circle, we need to use the formula C = πd, where C represents the circumference, π (pi) is a mathematical constant approximately equal to 3.14159, and d is the diameter of the circle.
In this case, the ratio of the circumference to the diameter is given as 22:7. Using this ratio, we can rewrite the formula as:
C/d = 22/7
Now we can substitute the given diameter (d = 15.6m) into the equation and solve for C:
C/15.6 = 22/7
To solve for C, we need to isolate it on one side of the equation. We can do this by multiplying both sides of the equation by 15.6:
C = (22/7) * 15.6
Now, let's calculate the value of C using a calculator:
C ≈ (22/7) * 15.6 ≈ 49.7142857m
Therefore, the circumference of a circle with a diameter of 15.6m is approximately 49.71 meters.
