The circumference of the earth is given.  24,901

What is the diameter of earth? Round your answer to the nearest tenth. Use 3.14 for π.

Enter your answer in the box below.

D ≈ 7,930.25

Step-by-step explanation:

The circumference is Dπ

D ≈ 7,930.25

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
