Need to calculate the volume of barbell

Sphere:

r = 10 cm

Bar:

h = 15 cm

d = 1 cm

sv = sphere volume

cv = cylinder volume

total volume of barbell given = 8380.5 cm3

My code:

% Your script goes here
r = 10
h = 15
d = 0.5
sv = (4/3)*pi*(r^3)
cv = pi*(d^2)*h
total = (2*sv) + cv

r = 10

h = 15

d = 0.5000

sv = 4.1888e+03

cv = 11.7810

total = 8.3894e+03

This is the error i am getting:

Check if the required variables are present and assigned correctly?

Variable cv has an incorrect value.

Hello,

You probably entered the d value incorrectly! Set the d value to 0.25.

r = 10
h = 15
d = 0.25
sv = (4/3)*pi*(r^3)
cv = pi*(d^2)*h
total = (2*sv) + cv
