Answer:
78.95cm^2
Step-by-step explanation:
The equation for a cylinder is rπ^2 · h
2π²·4≈78.95
1) 84 hours
2) 2.4 meters
3) 4800 seconds
4) 100000grams
5)219.2 Fahrenheit degrees
Step-by-step explanation:
Opposite angles in a cyclic quadrilateral are supplementary.
Therefore 3c = 4d = 180°, c = 60° and d = 45°.
Step-by-step explanation:
At d, f'(x) is increasing (concave up), but it is not positive. The tangent line at that point has a negative slope.
