The ratio of the circumference of a circle to its diameter is 22:7.what is the circumference of a circle of diameter 15.6m?
x/15.6 = 22/7
Well, if we use the ratio 22:7 to figure this out, we know that for every 22 units of circumference, there are 7 units of diameter. So, to find the circumference of a circle with a diameter of 15.6m, we can set up a proportion:
22/7 = x/15.6
Now, let's cross multiply:
7x = 22 * 15.6
Solving for x, we get:
x = (22 * 15.6) / 7
And the answer is...
Drumroll please...
Approximately 49.71m!
So, the circumference of a circle with a diameter of 15.6m is about 49.71 meters. Now that's quite a round number, don't you think?
To find the circumference of a circle, you need to multiply the diameter by the ratio of the circumference to the diameter. In this case, the ratio is given as 22:7.
First, let's calculate the circumference using the formula:
Circumference = Pi * Diameter
Given:
Diameter = 15.6 m
Pi is a mathematical constant, commonly approximated as 3.14159.
Now, let's plug in the values and calculate:
Circumference = 3.14159 * 15.6
Circumference = 48.978024
So, the circumference of a circle with a diameter of 15.6 m is approximately 48.98 meters.
To find the circumference of a circle, we can use the formula:
Circumference = π * Diameter
Given that the ratio of the circumference to the diameter is 22:7, we can use this information to find the value of π (pi).
Let's set up a proportion:
Circumference / Diameter = 22/7
Substituting the given values:
Circumference / 15.6 = 22/7
Next, we can cross-multiply to solve for the circumference:
Circumference = (22/7) * 15.6
Simplifying the expression:
Circumference = 49.7 m
Therefore, the circumference of a circle with a diameter of 15.6 m is 49.7 m.
