Answer:
A = 27 ft²
Step-by-step explanation:
A = 6*8 - 3*2 - 3*5
A = 48 - 6 - 15
A = 27
Answer: 159 miles because 10.6 times 15 = 159

Answer:
the cost function is Cost=7000 m*$ /R + 50.265 $/m² * R²
Step-by-step explanation:
then the cost function is
Cost= cost of side area+ cost of top + cost of bottom = 2*π*R*L * 5$/m² +
π*R² * 8$/m² + π*R² * 8$/m²
since the volume V is
V=π*R²*L → V/(π*R²)=L
then
Cost=2*π*R*V/(π*R²) * 5$/m² + π*R² * 8$/m² + π*R² * 8$/m²
replacing values
Cost=2*700 m³ /R * 5$/m² + π*R² * 16$/m² = 7000 m*$ /R + 50.265 $/m² * R²
thus the cost function is
Cost=7000 m*$ /R + 50.265 $/m² * R²
Regroup terms
p - 3/4 = 1/2
Add 3/4 to both sides
p = 1/2 + 3/4
Simplify 1/2 + 3/4 to 5/4
<u>p = 5/4</u>
