Solution:
<u>Note that:</u>
- 2πrh + 2πr² = Area of cylinder formula
- Radius = 4 m
- Height = 8 m
<u>Finding the surface area:</u>
- 2πrh + 2πr²
- => 2(π)(4)(8) + 2(π)(4²)
- => 64π + 2(π)(16)
- => 64π + 32π
- => 96π m²
Answer:
P=3T-50
Step-by-step explanation:
Form the given four values we can assume a linear relationship between profit and the no of tickets sold.
Let the equation corresponding to that be some P=aT+b.
Now substitute the first set of values(100,50) in the above equation we get
100=50a+b.
Now substituting second set of values (100,250) we get 250=100a+b.
Let these equations be eq1 and eq2.
Now substract eq1 from eq2 we get 50a=150 or a=3.
Substitite value of a in one of the equations we get b=-50.
∴P=3T-50
