Find the area of the circle.Use 22/7 as pi.
this is 6th grade work sorry i have been stuck for an hole hour
you don't say whether the radius, diameter, circumference is 28.
Anyway, just plug in the formula:
A = πr^2
To find the area of a circle, you need to know the radius or the diameter. The radius is the distance from the center of the circle to any point on the circumference, and the diameter is the distance across the circle passing through the center.
In your case, if you have the diameter, you would need to divide it by 2 to find the radius.
Once you have the radius, you can use the formula for the area of a circle, which is A = πr^2, where A represents the area and r represents the radius.
Since you have been given (22/7) as an approximation for pi, you can substitute it into the formula as follows:
A = (22/7) * r^2
So, if you are given the value of the radius, you can square it, then multiply by (22/7) to find the area.
If you are given the diameter instead, you can divide it by 2 to find the radius, then proceed with the formula above.
For example, let's say the radius is 5 units. Substitute the value of the radius into the formula:
A = (22/7) * 5^2
A = (22/7) * 25
A = 550/7
A ≈ 78.57 square units
Therefore, the approximate area of the circle with a radius of 5 units is 78.57 square units.
oh sorry i forgot to put this on there
it is 28cm
