Calculate the volume of the cylinder

The volume of the cylinder is 502.4cm³

Step-by-step explanation:

To calculate the volume of a cylinder we have to use the following formula:

v = volume

h = height = 10cm

π = 3.14

r = radius = 4cm

v = (π * r²) * h

we replace the unknowns with the values we know

v = (3.14 * (4cm)²) * 10cm

v = (3.14 * 16cm²) * 10cm

v = 50.24cm² * 10cm

v = 502.4cm³

The volume of the cylinder is 502.4cm³

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
