The answer is 6 degree.
Step by step process
The formula for calculating the measure of each exterior angle of a polygon is (360/n).
The number of sides of 56-gon(n) = 56.
So, each exterior angle
= (360/56)
= 6.43 or
6(approximately)
The correct choice would be 128.
If there are 6 options and the person can pick any number of toppings, we need to know the number of subsets that can be formed with 6. That would be 2^6 or 64.
Since there is a pan or hand-tossed option, we need to multiply 64 by 2 to find the total.
64 x 2 = 128
The answer is 2^12 = 4096.
Look at a tree diagram. With one spin there are two possible outcomes (branches). Every time you spin, each of the branches split into two more branches.
With 12 spins, first there are 2 branches, then 2*2, then 2*2*2, ... In the end it's 2^12
Circumference = 2pi * r
So
3pi = 2pi r divide away pi
3 = 2 r
(3/2) = r = 1.5 m
Area = pi ( r^2) = pi (1.5)^2 = 2.25 pi m^2 ≈ 7.07 m^2
