Answer:
V = 15.7*x^2 + 125.6*x + 251.2 I'd use this as an answer, but it depends how you have been told to treat pi. This answer is also possible.
V = 5*pi*x^2 + 40*pi*x + 80*pi
I can't really tell you which one to use.
Step-by-step explanation:
Givens
V=pi*r^2 * h
pi = 3.14
r = (x + 4)
h = 5
Solution
V = pi * (x + 4)^2 * 5
V = pi * (x^2 + 8x + 16)*5
V = pi * (5x^2 + 40x + 80) Now the question is what to do with pi.
V = 5*pi*x^2 + 40*pi*x + 80*pi
That one possible answer. The other is to give pi a value
V = 15.7*x^2 + 125.6*x + 251.2

Answer:
38 cm²
Step-by-step explanation:
The shaded shape is composed of two rectangles.
A horizontal rectangle at the top of the T shape and a vertical rectangle.
area of horizontal rectangle = 2 × (2 + 3 + 5) = 2 × 10 = 20 cm²
area of vertical rectangle = 3 × 6 = 18 cm²
shaded area = 20 + 18 = 38 cm²
