Answer:
<h3>
A. A = 66π cm² ≈ 207.35 cm²</h3><h3>
B. No, will not. {will be less than double}</h3><h3>
C. No, will not. {will be more than double}</h3>
Step-by-step explanation:
<h3>
A.</h3>
h = 8 cm, r = 3 cm
A = 2×πr² + 2πr×h = 2πr×(r + h)
A = 2π×3×(3 + 8) = 66π cm² ≈ 207.35 cm²
<h3>
B.</h3>
h = 2×8 = 16 cm , r = 3 cm , 2×66π = 132π cm²
A = 2π×3×(3 + 16) = 114π cm² ≠ 132π cm²
<h3>
C.</h3>
h = 8 cm , r = 2×3 = 6 cm , 2×66π = 132π cm²
A = 2π×6×(6 + 8) = 168π cm² ≠ 132π cm²
Answer:
a. C = 7x
b. $1820
Step-by-step explanation:
Let the number of students the bus carries be x.
a. It costs $7 for every student that they bus.
Therefore, the cost of the school hiring the bus is:
C = 7 * x
C = 7x
b. To bus 260 students, then, the cost will be:
C = 7 * 260
C = $1820
Given that the first number shows up as four. The second number should be six so that the sum would be ten. Therefore, its probability should be 1/6.
