F(4) is equivalent to 28 because when you plug in 4 for the x, you get 28.

Answer:

f(4)=28

Step-by-step explanation:

Let f(x) = 3x + x², find f(4).

f(x) is a function such that the value of x at any time gives the value of 3x + x².

So when we are given the value of f(x), we just input the value of x in the equation and solve. Assuming were looking for f(0),

f(0) = 3×0 + 0²= 0

From the question given

Let f(x) = 3x + x², find f(4)

we would put x=4 in 3x + x²

This would give 3×4 + 4²=12+16=28

So f(4) = 3×4 + 4²=12+16=28

What is the volume of a hemisphere with a diameter of 3.7 m, rounded to the nearest
lidiya [134]

Answer:

volume of the hemisphere  ≈13.3 m³

Step-by-step explanation:

To find the volume of the hemisphere, we will follow the steps below;

volume of a hemisphere = volume of a sphere/2

                                         = \frac{4}{3}πr³  /2

                                         =\frac{2}{3}πr³

from the question given, the diameter is 3.7 m, but diameter = 2×radius

radius = diameter /2   =  3.7/2 =1.85 m

π is a constant = 3.14

volume of a hemisphere = \frac{2}{3}πr³

                                          ≈  \frac{2}{3}×3.14 ×1.85³

                                           ≈13.3 m³

Therefore, volume of the hemisphere  ≈13.3 m³
