Answer:
Step-by-step explanation:
Okay so you are gonna substitute x for 5 so the equations will look like y= (5)2+(5)2
So 10+10 = 20
So y=20
Answer:
400
Step-by-step explanation:
Volume of a cone = 3.14 x 0.75^2 x 2/3
= 3.14 x 0.5625 x 2/3
= 1.76625 x 2/3
= 1.1775 = 1.18 feet^3
Because when you multiply by 10, it adds a zero to the end of the number, like 12*10 = 120, so vise versa for dividing
