Arotating sprinkler waters a circular region of a lawn with a diameter of 50 feet. what is the area of the lawn being watered? use 3.14 for pi. enter your exact value - do not

A =1962.5 ft^2

Step-by-step explanation:

We want to find the area of the circle

A = pi * r^2

We know the diameter

d = 2r

50 = 2r

Divide by 2

50/2 = 2r/2

25 =r

A = pi * (25)^2

A = pi*625

Let pi = 3.14

A = (3.14) * 625

A =1962.5 ft^2

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

its adding 5.5 each time
