Find the approximate area of the circle. Write your answer using 3.14 for T. 1 20 yd
62.8 yards squared
314 yards squared
20 yards squared
10 yards squared
Oh

b. 314 yards squared

Step-by-step explanation:

Area of a circle = πr²

radius (r) of the circle = ½(20yd) = 10 yd

π = 3.14

Plug in the values into the formula

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
