Use a cret formulative to find the area of a circle that if the diameter is twenty one round to the nearest hundred's place , use three point 14
To find the area of a circle, the formula is A = πr^2, where A represents the area and r represents the radius of the circle. However, since you provided the diameter instead of the radius, we need to convert it first.
Given that the diameter is 21, we can find the radius (r) by dividing the diameter by 2:
r = 21 / 2 = 10.5
Now, we can substitute the radius value into the formula and calculate the area:
A = 3.14 * (10.5)^2
A = 3.14 * 110.25
A ≈ 345.795
Therefore, the area of the circle, rounded to the nearest hundredth's place, is approximately 345.80 square units.
