The volume of sphere is
feet cubed.
Step-by-step explanation:
Given,
Surface area of sphere = 196π square feet
Surface area of sphere = 4πr²
We will find radius of sphere.

Dividing both sides by 4π

Taking square root on both sides

The radius is 7 feet.
Volume of sphere = 

The volume of sphere is
feet cubed.

Consecutive integers = in this situation double-digit whole numbers
So as there are 3 of them let's say 2 are 11 because that would be the highest consecutive number so 11+11= 22 and 48-22=26 so the three have the ages of 11,11,26 and the oldest would be 26 ;)
The answer would be 7.42

A1 = 0.91
a6 = -0.14
sum = (0.91+-0.14) /2
sum = 2.31
