Question

PLEASE HELP. I'M DESPERATE! 100 POINTS AND BRAINLY IF CORRECT!
The formula for the volume of a right circular cylinder is
V = πr² h. If r = 2b and h = 5b +3 then what is the
volume of the cylinder in terms of b?
A 10b2 + 67b
B 20πb³ + 12πb²
C 20π²6³ +12π²b²
D 50пь3 + 20пb2 + 90nb

Answer 1

Answer:

B) 20πb³ + 12πb²

Step-by-step explanation:

V = π (2b)^2 * (5b + 3) = π 4b^2 * (5b +3) = π ( 20b^3 + 12b^2) = 20πb³ + 12πb²

Answer 2

Answer:

B. 20πb³ + 12πb²

Step-by-step explanation:

The equation for the volume is incorrect, the volume of a cylinder with radius (r), and height (h), is πr²h.
