Answer:
length of segment AB is 13
OR
AB = 13
Step-by-step explanation:
Use the Pythagorean Theorem with c being the length of segment AB.
a^2 + b^2 = c^2
5^2 + 12^2 = c^2
169 = c ^2 (square root both sides to get c by itself)
13 = c
Just choose any combination so that a is negative and b is positive, and vice versa. For example, if a = 3 and b = -6, |3-6| ≠ |3| + |-6|.
This is because |-3| = 3, and |3|+|-6| = 3+6 = 9.
3≠9.
Answer: 3 1/3 ft^2
Step-by-step explanation:
Start by converting the inches into feet
1 ft = 12 in
4 in/1 x 1 ft/ 12 in = 4/12 ft = 1/3 ft
Now, imagine just multiply like normal for a rectangle:
Area of a rectangle = base x height
Area of rectangle = (10 ft) (1/3 ft)
Area of rectangle = 3 1/3 ft^2
First, set up the formula.
V=pi*r^2*h
Substitute 10 for r and 15 for h.
V=pi*10^2*15
V=pi*100*15
V=pi*1500
V=4710 cubic feet
It takes 4710 cubic feet of water to fill the well.
