Question
Question 11 of 25To the nearest hundredth, what is the circumference of a circle with a radius of 7 units?A.43.98 unitsB.21.99 unitsC.35.75 unitsD.153.94 units
Solution
The circumference of a circle is calculated by the formula 2πr, where r is the radius of the circle.
Step 1: Substitute the given radius, which is 7 units, into the formula.
Circumference = 2π * 7
Step 2: Calculate the value.
Circumference = 2 * 3.14 * 7 = 43.96 units
So, to the nearest hundredth, the circumference of a circle with a radius of 7 units is 43.96 units. Therefore, the answer is A. 43.98 units.
