Step-by-step explanation:
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:
x=9
Step-by-step explanation:
-5 square root x =-2+3
5x=4x^2 −12x+9
Simplify 25x-4{x}^{2}+12x-925x−4x 2 +12x−9 to 37x-4{x}^{2}-937x−4x 2-9
then...
(4x−1)(x−9)=0
x=1/4,9
-drop 1/4
x=9
Answer:
c. 44,950,000
Step-by-step explanation:
The following table is missing:
Year Attendance (millions)
1985 18.4
1990 25.2
1995 33.1
2000 37.6
Using a calculator, the line of best fit is obtained. Equation:
y = 1.31x - 2581.6
where y is attendance (in millions) and <em>x</em> is the year. Replacing with x = 2005 into the equation, we get:
y = 1.31(2005) - 2581.6
y = 44.95 millions or 44,950,000
