Answer:
Yes
Step-by-step explanation:
Given a number, a
Square of number = a²
Square root of number = √a² = a
Assume a = 4
The square of 4 = 4² = 16
The square root of 16 = √16 = 4
Hence, Grogg is correct

Answer:
3
Step-by-step explanation:
We know the formula is pi * r^2 * h, so we can do 108/12.
We end up getting 9. Then we take the square root of 9 since 9 = r^2 so our r does equal to 3
1/2 = 0.5 = 50% was found.
Looking at the scale, there are 5 dashes from 0 to 10,000. This means that each dash is worth $2,000. The thermometer is marked 2.5 dashes up; 2.5(2000) = 5000.
5000/1000 = 1/2; 1/2 = 0.5; 0.5 = 50%.
