PLS HELP ITS MY FINAL EXAM What is the area of the base of the cone below? A cone with height 12 feet and volume 90 feet cubed.

hoa [83]

Answer:

$A=22.5\ \text{feet}^2$

Step-by-step explanation:

We have,

Height of a cone is 12 feet

Volume of the cone is 90 feet

It is required to find the area of the base of the cone.

The base of a cone is circular in shape.

The formula used to find the volume of a cone is given by :

$V=\dfrac{1}{3}\pi r^2 h$

here, $\pi r^2=A$ (area of base of cone)

$V=\dfrac{1}{3}\times Ah\\\\A=\dfrac{3V}{h}\\\\A=\dfrac{3\times 90}{12}\\\\A=22.5\ \text{feet}^2$

So, the area of the base of the cone is $22.5\ \text{feet}^2$ .

Tre's walk from his house to the bus stop is of a mile. He is able to complete the walk each day in of an hour. What is Tre's wa

umka21 [38]

Tre's walking speed is 1mi/hr.

Data given;

distance = 1 mile
time = 1 hour

<h3>Speed or Velocity</h3>

This is the rate at which an object covers a distance within a particular time frame.

$speed = \frac{distance}{time}$

substituting the values into the equation

$speed = \frac{1}{1}\\ speed = 1 m/s$

Tre's walking speed is 1mi/hr

Answer:

x = 33.8°

Step-by-step explanation:

The resulting diagram we have is a right triangle. To find x, apply trigonometric function.

Reference angle = x

Opposite = 116

Adjacent = 173

Apply TOA:

Tan x = Opp/Adj

$tan (x) = \frac{116}{173}$

$x = tan^{-1}(\frac{116}{173})$

x = 33.8° (nearest tenth)
