Answer:
f(-2) = 3
Step-by-step explanation:
f(x) = x² + 3x +5
f(-2)=(-2)² + 3*(-2)+5
= 4 - 6 +5
= 3
You find out what you have to do to get three then one and so on
Answer:
67.014
Step-by-step explanation:
V = π r^2 (h/3)
(Volume equals pi r squared, h over 3)
Diameter is 4, so the radius is half of that = 2
Plug in the numbers
V = π (2^2) (16/3)
V = π (4) (5.333)
V = 3.14 x 4 = 12.566
V = 12.566 x 5.333
V = 67.014
Answer:
33
Step-by-step explanation:
The formula for solving the area of a Trapezoid is a+b/2*h if we substitute the value to 16+3/2*3 it will equal 33
