A bicycle wheel has a diameter of 24inches. <br> what is the area of the wheel?
goldfiish [28.3K]

Answer:

\large\boxed{A=144\pi\ in^2\approx452.16\ in^2}

Step-by-step explanation:

A diameter is two times longer than a radius. Therefore, if the diameter

d = 24in, then the radius r = (24in) : 2 = 12in.

The formula of an area of a circle:

A=\pi r^2

Substitute:

A=\pi(12)^2=144\pi\ in^2

\pi\approx3.14

Then

A\approx(144)(3.14)=452.16\ in^2

(Please Help)<br> Line s ‖ segment RP. <br> m∠3 = m∠__?
goldfiish [28.3K]
<span>before answering this question, we should know the properties of angles and parallel lines. For example, two angles are called interior alternate angles, if each angle is created by the existence of two parallel lines and a an another line called transversal. As for our case, 3 and 5 are alternate angles, so meas 3 = meas 5. It verifies Z test when we look at the figure.</span>

Which expression gives the distance between the points (2,5) and (-4, 8)?
german

Answer:

A. (2+4)² +(5-8)²

Step-by-step explanation:

To find then distance between two points, we will follow the steps below;

write down the formula

D = √(x₂-x₁)²+(y₂-y₁)²

(-4, 8)

x₁=-4

y₁ = 8

(2,5)

x₂=2

y₂=5

we can now proceed to insert the values into the formula

D = √(x₂-x₁)²+(y₂-y₁)²

   

   = √(2+4)²+(5-8)²

    =√(6)² + (-3)²

   =√36+9

   =√45

Therefore the expression which gives the distance between two the two points is  (2+4)² +(5-8)²
