Circumference = 2(pi)r
Area = (pi)r^2
r = 5
5 * 2 = 10
Circumference = 10π
5 * 5 = 25
Area = 25π
Using 3.14 as pi substitute:
5 * 3.14 = 15.7
15.7 * 2 = 31.4
Circumference = 31.4
5 * 5 = 25
25 * 3.14 = 78.5
Area = 78.5
Dont know the firat question but the propability is 43 out of 100 percent
Answer:
The answer would be A
Step-by-step explanation:
This is because when you take 1.625 it rounds back to 6 because 2 isnt more then 5 or 5 so it wouldn't round just like 1.635. I believe thats the answer im not positive
Two faces are 3*5 = 15; and because there are two faces you double to get 30;
5*8 = 40, double to get 80,
3*8 = 24, double to get 48, and we add:
48 + 30 + 80 = 158
