Plz help… A company makes steel rods shaped like cylinders. Each rod has a diameter of 4 centimeters and a height of 60 centimeters. If the company used 54,259.2 cm of steel, how many rods did it make?
Use 3.14 for “Pie” and do not round your
rods

i d k if its right

Step-by-step explanation:

4 centimeters + 4 centimeters = 8 centimeters = diameter

60 centimeters = height

volume =

Divide the total volume of the metal by the volume of one roid.

71 rods

Step-by-step explanation:

first we need to calculate the volume of 1 steel rode

diameter is 4, so radius = 2.

volume of right cylinder/ in our case steel rode =

volume =

if the company used 54,259.2 cm of steel, to calculate how many rodes it made, we divide 54,259.2 by 240

n = 54,259.2/240pi = 71.96 rods, or you can say 71 rods

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
