Find the circumference and area of a circle with the diameter of 10 inches leave your answer in terms of pi

The answer to your question is Circumference = 10π in

                                                                    Area = 25 π in²

Step-by-step explanation:

Data

diameter = 10 in

Process

1.- Find the radius

   radius = diameter/ 2

   radius = 10/2

   radius = 5 in

2.- Find the circumference

   Circumference = 2πr

-Substitution

   Circumference = 2π(5)

-Simplification

   Circumference = 10π in

3) Find the area

    Area = πr²

-Substitution

    Area = π(5)²

-Simplification

    Area = 25π in²      

step-by-step explanation:

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
