The formula for the area of a circle is pi*r^2. 3.14*16^2 = 803.84 centimeters squared
Answer:
a) 36°
b ) 18°
Step-by-step explanation:
The formula is given as:
The measure of each exterior angle =360°/n, where n = number of sides of a polygon.
a) decagon
Decagon = 10 sides
Hence, the measure of each exterior angle = 360°/10
= 36°
b) 20-gon
20-gon = 20 sides
Hence, the measure of each exterior angle = 360°/20
= 18°
Slope: -1 y- intercept: (0,8)
The 12 numbers of pi are 3.14159265359
