Answer:
1996.66.......
Step-by-step explanation:
The unit circle is a circle with radius

, so you have

where

is measured in radians, so

.
Answer: radius = 6.5millimeters; Area = 132.7m²
Step-by-step explanation:
The circumference of a circle = 2πr
The area of a circle = πr²
The circumference of a button is 40.8 millimeters. Then we can get the radius, thus will be:
Circumference = 2πr
40.8 = 2 × 3.14 × r
40.8 = 6.28r
r = 40.8/6.28
r = 6.5
Radius is 6.5 millimeters
Area = πr²
Area = 3.14 × 6.5 × 6.5
Area = 132.7m²

Answer:
1. t<45° 2. d≥200
Step-by-step explanation:
t is less than 45°
it said no less than meaning you can spend 200 or more to get the discount so that means d≥200
