Check the picture below.

as you can see, the angle at P is the inscribed angle, and the intercepted arc is AB, thus 2P = arcAB.

and since a circle has a total of 360°, the other arc is just 360 - arcAB.

The length of the arc cannot be found without knowing some linear measure of the circle. None are given.

The measure of arc AB is twice that of angle APB, so is
   2*108° = 216°.
The measure of arc APB is the difference between that and 360°, so is
   360° -216° = 144°.

Given data

Lenght of book=  11.2 inches

WIdth of book= 7.3 inches

We know that Area= Length* Width

The height of a cylinder is 5 centimeters. The diameter of the base of the cylinder is 16 centimeters. Find the lateral surface
soldier1979 [14.2K]

Answer:

Lateral surface area of the cylinder =251.2 cm^2

Step-by-step explanation:

  Lateral surface area of he cylinder = 2*\pi*r*h  i.e area of side surface.

Height(h) = 5 cm

Diameter = 16 cm

radius(r)= 16/2= 8 cm

Lateral surface area of the cylinder = 2*\pi *8*5                        

                                                                         \pi =\frac{22}{7}=3.14

               L.S.A=  2*3.14*8*5

              L.S.A=  251.2 cm^2

The lateral surface area of the cylinder with radius 8 cm and height 5 cm is 251.2 cm^2
