The diameter of earth's moon is on average m. use the formula to find the approximate surface area. (use 3.14 for the value of .) to find the surface area

3.14 * m2

Step-by-step explanation:

You need to use the surface formula of sphere:

4 (pi) r^2

The radio r is the half of the diameter, which in this case is m. So r = m/2

Surface= 4*(3.14)(m/2)^2

= 4*3.14*(m^2)/(2^2)

= 4 * 3.14 * m^2 / 4 { here we can cancel the numbers 4, as one multiplies an the other divides)

= 3.14 * m^2

Replace the m for its value and get the surface.

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
