answer:

V=πr2h

Step-by-step explanation:

3.14(3)^2 (5) = 141.3

3.14(5)^2 (3) = 235.5

The perimeter of the rectangle is 80cm

Step-by-step explanation:

Since the are of it is 144cm^2 and the length is given as 36 cm. You just need to divide the area and the length of it then what you'll get is the width of it.

144/36=4cm

Area=144cm

Length=36cm

Width=4cm

Now that all givens are found,you just need to add the width and the length to find the perimeter of it

P=2(length+width)

= 2(36cm+4cm)

=2(40)

P=80cm

The perimeter of the rectangle is 80cm
