A circle has a radius of 8 inches what is the area in terms of pi

4pi in2

8pi in2

18 pi in2
64 pi in2

i dont know pi

Step-by-step explanation:

The radius is 18 feet.

Step-by-step explanation:

The radius is half the diameter, or . The diameter of this circle is 36 feet, so the radius is feet.

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
