Answer:
- C. π(3in)2(12in) − 9(four over threeπ(1.5in)3)
Step-by-step explanation:
Volume of water is the difference of volume of vase at 12 in height and the total volume of marbles.
<u>Volume of cylinder up to water level:</u>
- Vs = πr²h = π(6/2)²(12) = π×(3 in)²×(12 in)
<u>Volume of marbles:</u>
- Vm = 9(4/3πr³) = 9×(4/3×π(3/2)³) = 9×(4/3×π×(1.5 in)³)
<u>Volume of water:</u>
- Vw = Vs - Vm = π×(3 in)²×(12 in) - 9×(4/3×π×(1.5 in)³)
Correct choice is C
Answer:
Approx = Area = 200.96in^2 when using 3.14 for approx.
A = 201.16in ^2 for calculator.
Step-by-step explanation:
A=πr2
A=3.14 x 8^2 = 64π
A = 201.16in ^2 when using true decimals of pi on calculator
A = 200.96in ^2 Approx 3.14 calculation.
So it is important to actually remember pi as equal to 3.14159 for preciseness.
and not 3.14,
3.14
