Answer:
200.96 inches^2
Step-by-step explanation:
Area= pi*radius ^2=pi*8^2=64*pi=64*3.14=200.96 inches^2
Answer:
20 ≤ x ≤ 70
Step-by-step explanation:
Given that:
30 ≤ x + 10 ≤ 80
By solving the left half inequality first:
30 ≤ x + 10
Subtracting 10 from both sides:
30 - 10 ≤ x + 10 -10
20 ≤ x
Now solving inequality of right half:
x + 10 ≤ 80
Subtracting 10 from both sides:
x + 10 -10 ≤ 80 - 10
x ≤ 70
So after simplification we get:
20 ≤ x ≤ 70
