What is the area of this circle use 3.14 81 243.06 254.34 300

254.34

Step-by-step explanation:

The formula for area of a circle is given by

A = pi * r^2

A = pi * 9^2

A = 81*pi

Using 3.14 as an approximation for pi

A = 3.14*81

A = 254.34

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
