Question

Can someone help me out? i don't get it

Answer 1

Answer:

637π & 45π

Step-by-step explanation:

• The formula for the volume of a cylinder is V=Bh or V=πr²h,
• where B- base area, h- height, r- radius of base

Q4.                                  

You have:

r= 7 in

h=13 in

Then,

V=πr²h=π*7²*13 = 637π

Q5.                                    

Same as above:

d=6 m => r=d/2= 3 m

h=5 m

V=πr²h=π*3²*5 = 45π

Hope it helps
