If a baseball is a sphere with a radius of 3.75 cm, what is the surface area of the baseball? Use
π= 3.14.

176.625 cm^2

Step-by-step explanation:

The surface area of a sphere is given by

SA = 4 pi r^2

     = 4 * 3.14 * (3.75)^2

     = 176.625 cm^2

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
