The circumference of a circle is 6π inches. What is the area of the circle? Alternative Text A. 3π in.2 B. 9π in.2 C. 12π in.2 D. 36π in.2

B) 9π in^2

Step-by-step explanation:

Circumference of a circle is C = πD

Divide 6π by π to get 6 then divide by 2 to get the radius of the circle

Area of a circle is A = πr^2

6/2 = 3 3 = r

π(3)^2 = 9π

16

step-by-step explanation:

2 x 40 = 80

80/5

= 16

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
