The diameter of a pizza is 14 inches what is the circumference of the pizza use 3.14

153.86

Step-by-step explanation:

Circumference = pi x radius squared.

To find the radius of a diameter it would diameter divided by 2, which would be 7 inches here.

C = 3.14 x 7^2

C = 3.14 x 49

C = 153.86

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
