Step-by-step explanation:
● formulas of valume = πr²h
- 22/7×12×12×38•4 ft
- 3•14×144×38•4 ft
- 452•16×38•4 ft
- 17362•944 ft³
● now nearest to the number
- 17262•944 ft³ nearest tenth is 17360ft³.

Answer:A
Step-by-step explanation:
Answer:
C. (0.9, 0.3)
Explanation:

The above given equation is critical to solve algebraically thus they have mentioned to solve it using a technology - graphing calculator.
<h3><u /></h3><h3><u>When graphed the following equations</u>:</h3>
They meet each other at: (0.9371, 0.2728)
(0.9, 0.3)
Step-by-step explanation:
the lengths OB, OC & BC together forms a isosceles triangle.
therefore,
OB=OC
3x+4=x+8
2x=4
x=2.
OB = 3x+4= 3.2+4=10cm.
OC= x+8= 2+8=10cm.
therefore, the diagonals are : 20cm each.
hope this helps you.
