Answer:

measure of major arc BEA = 224.4°       Option D

Step-by-step explanation:

Given that, measure of inscribed angle ∠BEA = 67.8°

Firstly we will find the central angle.

Suppose O is the center of given circle

So, ∠AOB = 2∠AEB

∠AOB = 135.6°

The measure of arc AB  is same as the measure of its central angle.

So, measure of AB arc = 135.6°

Now complete circle measure = 360

Measure of major arc AEB = 360° - measure of arc AB

                                           =  360°  -135.6°

                                           = 224.4°

That's the final answer.

A lab technician made a 14 cm diameter hole through the middle of a cylinder that has a diameter of 20 cm and a height of 28 cm.
Step2247 [10]

Answer:

The volume of the finished cylinder is 4486.2 m^3

Step-by-step explanation:

To find the volume of the finished cylinder, we have to first find the volume of the hole (with 14 cm diameter and a height of 28 cm) and subtract it from the volume of the original cylinder (with diameter of 20 cm and a height of 28 cm).

Note: The hole is also cylindrical in shape.

The volume of a cylinder is given as:

V = \pi r^2h

where r = radius, h = height

VOLUME OF THE HOLE

The diameter of the hole is 14 cm, hence, its radius is 7 cm (14 / 2 = 7)

Its volume is:

V = \pi *7^2 * 28\\V = 4310.3 m^3

VOLUME OF THE ORIGINAL CYLINDER

The diameter of the cylinder is 20 cm, hence, its radius is 10 cm (20 / 2 = 10)

Its volume is:

V = \pi *10^2 * 28\\V = 8796.5 m^3

Hence, the volume of the finished cylinder will be:

8796.5 - 4310.3 = 4486.2 m^3

The volume of the finished cylinder is 4486.2 m^3
