Looks like you meant to write (p/q)³ if so it's power of a quotient
Answer:
The circumference of the circle is 52π
Step-by-step explanation:
To solve this exercise we first have to calculate the radius of the circle, for this we will use the formula of area of a circle and we will clear the radius
a = area = 676π
r = radius
a = π * r²
we clear r
r = √(a/π)
now we replace the known values
r = √(676π/π)
r = √(676)
r = 26
now we use the formula to calculate the circumference of a circle
c = π * 2r
c = π * 2 * 26
c = 52π
The circumference of the circle is 52π
You have to plug them in to see each solution, so the answers that apply would be 65 and 66 all the other answers are less than or equal to 8
The correct answer is: [A]: " 384 in² " .

Explanation:

The formula for the surface area of a cube is:
______________________________________________________
→ A = 6a² ;
______________________________________________________ → in which:
______________________________________________________
A = surface area of the cube— for which we shall solve ;
(in "square units" ; or, " in² " ; in our case) ;
a = side length = " 8 in " (given);
→ Note: A cube has all equal side lengths.
→ The "6" in the formula accounts for "6 sides" of a cube.
_______________________________________________________
→ To solve for the surface area of the cube; plug in our known value(s);
& solve; as follows:
_______________________________________________________
→ A = 6 a² ;
= 6 * (8 in)² ;
= 6 * 8² * in² ;
= 6 * 8 * 8 * in² ;
= 48 * 8 * in² ;
= 384 in² ;
_______________________________________________________
The answer is: " 384 in² " ;
→ which is: Answer choice: [A]: " 384 in² " .
