Find the circumference of a circle whose diameter is 3.2 inches

10.048 inches

Step-by-step explanation:

The circumference of a circle is given by

C = pi*d

     3.14 * 3.2

    10.048 inches

c = 10.48 inches

Step-by-step explanation:

c = pi*d

pi = 3.14

d = 3.2 inches

c = 3.14*3.2

c= 10.48 inches

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
