The answer is 16
When a number is raised to a fraction you basically look at it in two ways.
The denominator tells you what # root you have to take so in this case it is 3 so that means that first you take the cubed root of the number 64 which is four.
The numerator then tells you how many times to multiply that number by its self. So in this case you take 4 and you mulitply by itself 2 times so 4*4 is equal to 16
Answer:
y =5x
Step-by-step explanation:
5+8=13
The area of the regular octagon is calculated as half of the product of the perimeter and the apothem (ap), using the formula of the area of the regular polygon.
We have then:
A = ((p) * (ap)) / 2
Where,
p: perimeter
ap: apotema
Substituting values:
A = ((8 * 3.4) * (4.2)) / 2
A = 57.12 in ^ 2
Answer:
the area of the regular octagon is:
B. 57
