By completing this quiz you are going to be prepared for the final exam on surface area and volume of a cylinder.

• 1.

### What is the formula for a cylinders surface area?

• A.

2*(r*r*h*3.14)+h*d*3.14

• B.

2*(r*r*3.14)+h*d*3.14

• C.

2*(r*r*3.14)*h*d*3.14

• D.

2*(r+r+3.14)+h*d+3.14

B. 2*(r*r*3.14)+h*d*3.14
Explanation
The formula for the surface area of a cylinder is given by 2*(r*r*3.14)+h*d*3.14. This formula accounts for both the area of the two circular bases (2*(r*r*3.14)) and the area of the curved side (h*d*3.14). By adding these two components together, we obtain the total surface area of the cylinder.

### What is the formula for a cylinders volume?

• A.

R+r*h*3.14

• B.

R*r*h+3.14

• C.

R*r+h+3.14

• D.

R*r*h*3.14

D. R*r*h*3.14
Explanation
The formula for calculating the volume of a cylinder is given by multiplying the square of the radius (r) with the height (h) of the cylinder and then multiplying the result by the value of pi (3.14). This formula, r*r*h*3.14, correctly represents the calculation for the volume of a cylinder.

### What would be the volume if: diameter=9cm and the height 11cm?

• A.

623.14

• B.

434.39

• C.

329.63

• D.

699.80

D. 699.80
Explanation
The correct answer is 699.80. To find the volume of a cylinder, we use the formula V = πr^2h, where r is the radius and h is the height. In this case, the diameter is given as 9cm, so the radius would be half of that, which is 4.5cm. Plugging in the values, we get V = 3.14 * (4.5)^2 * 11 = 699.80. Therefore, the volume of the cylinder would be 699.80.

### Is the circumference twice the diameter?

• A.

True

• B.

False

B. False
Explanation
The circumference of a circle is not twice the diameter, it is actually pi times the diameter. This is a fundamental property of circles and is known as the circumference formula. The value of pi is approximately 3.14, so the circumference is always greater than twice the diameter. Therefore, the answer is false.

### What is the unit for surface area?

• A.

Units^2

• B.

Units^3

• C.

Units^3.14

• D.

Units^2.2

A. Units^2
Explanation
The unit for surface area is represented by units^2. This is because surface area is a two-dimensional measurement, which is calculated by multiplying the length and width of a shape. The resulting value will have units squared, indicating that it represents the area of the surface.

### To find the radius of a cylinder you should measure the diameter and divide by 2 ?

• A.

True

• B.

False

A. True
Explanation
To find the radius of a cylinder, you need to measure the diameter and then divide it by 2. This is because the diameter is the distance across the center of the cylinder, and the radius is half of that distance. So by dividing the diameter by 2, you can determine the radius accurately. Therefore, the statement "To find the radius of a cylinder you should measure the diameter and divide by 2" is true.
