Mathematics

Answer:

Step-by-step explanation:

We will use the area of the circle to find the radius of the circle since that's all that that is useful for! If the area of the circle is 56 cm squared, then

56=\pi r^2  and

\frac{56}{\pi}=r^2  and

17.82535363=r^2 so

r = 4.222 cm

Now that we know that, we will use that.  But first, if we have a square circumscribed in a circle, then we know that from the center of the circle to any of the vertices of the square is the radius of the circle, 4.222. If we split that square into 4 triangles, pull one of those triangles out, we have a right triangle...45-45-90 to be specific.  Just for the sake of argument, put the 90 degree angle as the vertex angle of that right triangle and then split THAT triangle in half by dropping an altitude from the vertex angle to the base.  We still have a 45-45-90 triangle, but now the vertex angle is 45, one of the base angles is 90, and the other base angle is 45.  The hypotenuse of that triangle is the length of the radius we just found.  If the base angle is 45 and the hypotenuse is 4.222, we can use right triangle trig to find the length of the base of that triangle which, consequently, is half of the length of x, our unknown.

sin(45)=\frac{x}{4.222} and

4.222 sin(45) = x so

x = 2.9854

But don't forget that that x is only half the length of one of the sides of the square.  So multiply it by 2 to get that the side length, which is x, is

x = 5.97

Vol (pyr) = 1/3 b × h, where h = 15 and b = base = area of triangular base = 1/2 b×h, where h = 12 and b = 13
V = 1/3 (1/2×12×13)×15
V = (1/3×1/2×12)×13×15
V = 2×13×15 = 30×13 = 390 in^3

One important idea of the section "When Good Bananas Go Bad" is that experts say that we should grow only one type of banana in
Darina [25.2K]

Answer:

False

Step-by-step explanation:

According to the section, "When Good Bananas Go Bad", we are made to understand that one of the reasons why the TR4 fungus can spread easily through banana roots is because, there is only one variety, which is the Cavendish variety. Experts advise that people should develop interest in other varieties like the Manzano, which has the taste of Apple and Strawberry.

Another reason given for the spread of the disease is increased human transportation. Although growing one type of banana would be beneficial for companies, the fact that they have the same genetic material, aids the spread of the disease. So, diversification is advised.
