Step-by-step explanation:
We have,
Diameter of cylinder, d = 39.2 mm
Radius, r = 19.6 cm
Height of the cylinder, h = 39.2 mm
It is required to find the surface area of this cylinder. The formula of the surface area of cylinder is given by :

Putting all values we get :

Answer:

Step-by-step explanation:
The given function is
Let

Interchange x and y.

Solve for y,

Divide both sides by 2

Therefore;

Answer:
a. 
b. x = 10
Step-by-step explanation:
a. The number of home runs hit by Jack last season = x
It is given that Henry hit 3 more than half as many home runs as Jack hit.
Half of the runs hit by Jack = 
3 more than half the runs = 
So, the number of home runs hit by Henry = 
But, it is given that Henry hit a total of 8 runs.
Therefore, 
b. 
Subtract 3 from both sides.

= 5
x = 5 × 2
= 10
Hence, Jack hit 10 runs in the last season.
