Answer:

Area of triangle is:

40 square feet

Step-by-step explanation:

We are given a cone that has  radius=4 ft

and height=10 ft

We have to find the area of the triangle formed by a perpendicular cross-section through the cone’s center.

The triangle has base equal to the diameter of the cone=8 ft

(Since, diameter=2×Radius)

and height of triangle=height of cone=10 ft

Hence, Area of triangle=\dfrac{1}{2}\times base\times height

                                      =\dfrac{1}{2}\times 8\times 10

                                      = 40 ft²

Hence, area of triangle is:

40 square feet

Answer:

The circumference and diameter of a circle

Step-by-step explanation:

Proportional relationships can be written as y=kx, where k is some constant of proportionality. The formula for a circumference of a circle can be written as C=d\pi, where d is the diameter of the circle. Therefore, the constant of proportionality is \pi and the circumference and diameter of a circle are in a proportional relationship.

I didn’t understand how to solve this, i’d be happy if someone explained thank you

Answer:

Option (E)

Step-by-step explanation:

\frac{a}{b}=\frac{c}{d}=k

\frac{a}{b}=k

b=\frac{a}{k} ------(1)

\frac{c}{d}=k

d=\frac{c}{k} -------(2)

Since, \frac{6a+24}{md+6b}=k

By substituting the values of b and d from equation (1) and (2),

\frac{6a+24}{\frac{mc}{k}+\frac{6a}{k}}=k

\frac{k(6a+24)}{6a+mc}=k

\frac{6a+24}{6a+mc}=1

6a + 24 = 6a + mc

mc = 24

m = \frac{24}{c}

Therefore, Option (E) will be the correct option.
