Question
Question 10 of 25To the nearest hundredth, what is the area of a circle with a radius of 3 units?A.18.85 square unitsB.29.61 square unitsC.28.27 square unitsD.9.42 square units
Solution
The area of a circle is calculated using the formula: Area = πr², where r is the radius of the circle.
Given that the radius of the circle is 3 units, we can substitute this into the formula:
Area = π(3)² = π(9) = 28.27 square units.
So, the answer is C. 28.27 square units.
