Ran in:
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
