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

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3
