Answer:
Area of the circle = 227.0095 cm^2
Explanation:
Given:
- Diameter (D) = 17 cm
- π = 3.142
To Find:
Area of the circle
Soln:
We know that,
Area of the circle: πr²
where:
But we don't know the radius,as the diameter is given.We could use the formula of diameter & plug the value of it do find the radius.
Where
Substitute the value of Diameter:
Diameter = 2r
17 = 2r
17/2 = r
8.5 = r
r = 8.5
Now we got the radius, so substitute radius onto the formulae:
- Area of the circle = πr²
- Ar(circle) = π(8.5)²
- Ar(circle) = 72.25π(Answer in terms of π)
- Ar(circle) = 72.25 * 3.142
- Ar(circle) = 227.0095 cm^2
