Answer:
44,602.2 (c)
Step-by-step explanation:
The volume of a sphere is found by using the equation:
The radius is shown to be 22cm just plug it in and see that the equation produces the value: 44,602.2
Answer:
135°
Step-by-step explanation:
To convert from radians to degrees
degree = radian × 
Thus for 
degree = × ( cancel the π )
= 
= 
= 135°
Answer:
1. 6pi or 18.84cm
2. 20pi or 62.8cm
3. 13pi or 40.82cm
4. 9.5pi or 29.83cm
5. You calculate the circumference of a circle with the expression 2pi(r). r stands for the radius. You can also use pi(d), or pi x diameter.
7. You would use 2pi(r) to find the circumference of a circle when given the value of the circle's radius.
8. You would use pi(d) to find the circumference of a circle when given the value of the circle's diameter.

Answer:
Molly
Step-by-step explanation:
Brady did not properly create a square.
The square of a binomial is ...
(a -b)² = a² -2ab +b²
Where a²=x² and -2ab = -4x, you find b=2. The constant term in the square is 2²=4. Brady shows it as -4, which is incorrect.
Molly's work is correct.
