Using the formula for circumference from diameter (c=pi(d)), we find that the circumference of the ferris wheel is about 197.97 feet.  We then multiply that number by the revolutions to get 2,374.64 feet, which is the answer.

You are actually calculating "arc length."  The formula for that is s=r times theta,
where s is the arc length or distance traveled in a circle, and theta is the central angle (always in radians, never in degrees).

Actually, you could obtain the same result by using the formula for circumference of a circle.  The distance around the wheel is 2 pi r, where r is the radius and is one half of the given diameter.  calculate this circumference / distance, and then multiply your result by 2.

Note that your final answer MUST include units of measurement (of distance).

Nesterboy [21]

Answer:

x^2 -2x = 4x+1

2x^2 +12x = 0

9x^2 +6x -3=0

Step-by-step explanation:

A quadratic equation has the highest power of x being squared

x^2 -2x = 4x+1

2x^2 +12x = 0

9x^2 +6x -3=0

These are all quadratic equations

Find the lateral area of this pyramid whose base is a regular hexagon with a side length of 3cm and whose slant height is 12cm.
juin [17]

Answer:

108 cm^2

Step-by-step explanation:

The lateral surface area of a pyramid is given as

LSA= 1/2×perimeter of the base×slant height

base is hexagon with side 3 cm , therefore, perimeter of the base

=6×3=18 cm

slant height = 12 cm

thus, LSA = 1/2×18×12 = 108 cm^2
