A cylinder has a height of 13 centimeters and a radius of 4 centimeters. What is its volume? Use ​ ≈ 3.14 and round your answer
Roman55 [17]

Answer:

Volume of a cylinder = 653.12 cm³

Step-by-step explanation:

Volume of a cylinder = πr²h

Where,

Height, h = 13 cm

Radius, r = 4 cm

π = 3.14

Volume of a cylinder = πr²h

= 3.14 × (4cm)² × 13 cm

= 3.14 × 16 cm² × 13 cm

= 653.12 cm³

Volume of a cylinder = 653.12 cm³

1) How many 3/4 does it take to make 9/2?


     Now look at this, 3/4 x 6 = 4 1/2.  4 1/2 is the same as 9/2


   3/4 + 3/4 + 3/4 + 3/4 + 3/4 + 3/4 ---> takes 6, 3/4's to make 9/2

2)  How many 3/4's go into 9/2?


    This is the same question as the 1st one so the answer is 6 :)


3)  9/2 divided by 3/4 = ??


         Use the KEEP< CHANGE< FLIP method, so it turns into  I

                                                                                                    I
      9/2 x 4/3                       < -------------------------------------          I


  This is equal to 36/6 which is 6 :)


The answer is 6 for numbers 1, 2, and 3 :)
