Find the circumference of a circle that has a diameter of 1/6 yard use 22/7 for pi and reduce the fraction to simplest terms.

11/21 yards

Step-by-step explanation:

The circumference is the distance around the circle. It relates the number of times the diameter will encircle the circumference as 3.14 or π. As a result, the formulas for the circumference of a circle are C = 2πr or C = πd. Here the diameter is 1/6 and pi is written as a fraction 22/7. Substitute these two values and simplify the formula C = πd.

find the angular size of the equatorial radius of the earth, if the horizontal parallax of the sun

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
