Answer: D.  

The radius is 11 units, and the volume is 5,572.45 cubic units.

Step-by-step explanation:

We know that the volume of a sphere is given by :-

\text{Volume}=\dfrac{4}{3}\pi r^3, where r is radius of the sphere.

Given : The diameter of the sphere = 22 units

Then the radius of the sphere = \dfrac{22}{2}=11\text{ units}

Then , the volume of the sphere will be :-

\text{Volume}=\dfrac{4}{3}(3.14)(11)^3\\\\\Rightarrow\ \text{Volume}=5572.45 \approx\text{ cubic units}

Hence, the volume of the sphere =  5,572.45 cubic units

Antonio ran 129 laps at the park. Alan ran 20% more than that. how many laps did Alan run
Colt1911 [192]

Answer:

154.8

Step-by-step explanation:

20% is equal to 20/100= 0.20. So, 0.20 multiplied by 129 will give you 20% of 129 which is 25.8. If Alan ran 20% more then you add 25.8 to 129 which gives you an answer of 154.8.

Equation: 20/100= 0.2

                0.2* 129= 25.8

                25.8+129= 154.8

Alan ran 154.8 laps.
