28 points !!!! help
RoseWind [281]

Answer:

12 cm

Step-by-step explanation:

The area (A) of a trapezium is calculated as

A = \frac{1}{2} h (a + b)

where h is the perpendicular height and a, b the parallel bases.

Here A = 45, h = 5, a = 6 and b = ?, thus

45 = \frac{1}{2} × 5 × (6 + b) = 2.5(6 + b) = 15 + 2.5b ( subtract 15 from both sides )

30 = 2.5b ( divide both sides by 2.5 )

b = 12

The measure of the other parallel side is 12 cm

It takes a wheel 200 feet to complete 12 revolutions. Find the length of an arc of the wheel to the nearest hundredth created by
mr_godi [17]

Answer:

  2.65 feet

Step-by-step explanation:

Each revolution corresponds to a central angle of 2π radians, so 12 revolutions represent an arc of 24π radians. That means the arc length of 1 radian is ...

  (1 rad)(200 ft)/(24π rad) ≈ 2.65 ft

The length of the arc with a central angle of 1 rad is about 2.65 feet.
