volume of cylinders - item 20987 question 1 of 7
you have a can that is in the shape of a cylinder. it has a volume of about 1,728 cubic centimeters. the height of the can is 22 centimeters. what is the approximate length of the radius? use 3.14 for pi.

length of the radius is 5cm

Step-by-step explanation:

Use formula for Volume of a cylinder to calculate radius;

Volume of a cylinder =

= 3.14 (given)

Volume = 1,728

h = 22cm

r ; radius = ?

Plug in the numbers into the formula;

1,728 = 3.14 *

1,728 = 69.08

Divide both sides by 69.08 ;

1,728 / 69.08 =

25.014476 =

Find square root of both sides to solve for r;

r =5.0014

Therefore the approximate length of the radius is 5cm

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

168

step-by-step explanation:

i am pretty sure that the answer is 168
