Which is greater: 25% of 15 or 15% of 25? Explain your reasoning using algerbreaic representations or visual models
Bingel [31]
25% of 15 is the same as 15% of 25
25%=25/100
25% of 15=(25/100)15=(25*15)/100

15%=15/100
15% of 25=(15/100)25=(25*15)/100

Therefore:
25% of 15=15% of 25
because:
(25/100)15=(15/100)25
(25*15)/100=(25*15)/100

Help!!!!!!!!!!!!!!!!!!!
Marina CMI [18]

Answer:

Step-by-step explanation:

area of a cylinder = (area of a circle) times the (height)

area of a cylinder = π radius² × height

            radius = 57 cm        height = 40 cm

area of a cylinder  =   π 57² cm² × 40 cm

                              =   π (57² × 40) cm³

                              =   π ( 57 × 57 × 40) cm³             57x57 = 399 + 2850 = 3249  

                              =   π (3249 × 40) cm³

                              =    129969π cm³      π = 3.14

                              =    129969 × 3.14  cm³

                              =    408,074.4 cm³       < -----------------   Final Answer
