A cylindrical cardboard tube with a diameter of 8 centimeters and a height of 20 centimeters is used to package a gift. A cylinder has a height of 20 centimeters and a diameter of 8 centimeters. What is the approximate volume of the tube? Round to the nearest whole cubic centimeter. 1,005 cm3 1,340 cm3 3,351 cm3 4,021 cm3

4021 cm^3

Step-by-step explanation:

The volume of a cylinder can be found using the following formula.

where r is the radius and h is the height.

We know the cylinder has a height of 20 centimeters and a diameter of 8 centimeters.

h= 20 cm

d= 8 cm

Substitute these values into the formula.

First, evaluate the exponent.

8 cm^2= 8 cm * 8 cm= 64 cm

Multiply 64 cm^2 and 20 cm

Multiply 1280 cm^3 and pi

Round to the nearest cubic centimeter. The 2 in the tenth place tells us to leave the number as is.

The volume is about 4,021 centimeters^3.

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
