Answer:
Step-by-step explanation:
That composite figure is made up of a square and a quarter of a circle. We will first find the area of the square. Then we will find the area of the circle and divide it by 4.
Area of square = 1.6 × 1.6
Area of square = 2.56 m squared
Area of circle = (3.14)(1.6²) In case you forgot, the area of a circle is A = πr².
Area of circle = 8.0384
Divide that by 4 to get 2.0096.
Add 2.0096 to 2.56 to get the total area, which is
4.5696 or 4.6 rounded (choice D)

Step-by-step explanation:
Answer:
(a) 72 degrees
(b) 216 degrees
Let em know if you don't get how I answered either.
Step-by-step explanation:
So, to go all the way around is 360 degrees since there are 360 degrees. that means it turns 5 times for the beginning cd to be at the start again. So in 5 equal turns it goes 360 degrees. We want to know how much 360 is divided into 5 groups, or 360/5 = 72.
You can think of it this way, if it turns 72 degrees five times, it will have gone a full 360. that answers a though, each switch to another CD is 72 degrees.
b is asking how many degrees is it to go from 1 to 4. so how many movements is that? 1 to 2, 2 to 3 then 3 to 4. So 4. could have done 4-1 of course. anyway. 3 movements each 72 degrees is 72*3 = 216.
