Answer:
Pick the best solution.
Step-by-step explanation:
Volume of a cone is V = ⅓πr²h
If cone diameter is 4.3
V = ⅓π(4.3/2)²(5.2) = 25.17148... ≈ 25.17 ft³
If cone radius is 4.3
V = ⅓π(4.3)²(5.2) = 100.685950... ≈ 100.69 ft³
If cone diameter is 5.2
V = ⅓π(5.2/2)²(4.3) = 30.439938... ≈ 30.44 ft³
If cone radius is 5.2
V = ⅓π(5.2)²(4.3) = 121.75975... ≈ 121.76 ft³
Answer:
68
Step-by-step explanation:
Multiply the numbers to get the area
For example, the additive inverse of 12 is –12. The additive inverse of –3 is 3. Formally, the additive inverse of x is –x. Note: The sum of a number and its additive inverse is 0.
Answer:
14.38
Step-by-step explanation:
1. multiply the 5 packs of pencils times 0.79 each (5x0.79 = 3.95)
2. multiply the 8 packs of pens times 1.19 each (8x1.19=9.52)
3. add the total of pens and pencils together (3.95+9.52=13.44)
4. multiply 13.44 times 7% sales tax (13.44x.07=0.94)
5. add the total plus the sales tax (13.44+0.94=14.38
