Answer:
Step-by-step explanation:
Area is pi times r squared. I don't know how to write that on the keyboard. Take your pi(3.142) times the radius(6.2)squared. Pemdas tell us to do exponents first, so 6.2 squared is 38.44. To square a number, just multiply it times itself. So now, we have pi(3.142) times the squared radius(38.44). So, 3.142X38.44=

Answer:
D: x + (x+1) + (x+2) > 60
Step-by-step explanation:
Let
x = youngest brother age
x + 1 = older brother age
x + 2 = oldest brother age
Fathers age = 60
The inequality is
x + (x+1) + (x+2) > 60
x + x + 1 + x + 2 > 60
3x + 3 > 60
3x > 60 - 3
3x > 57
x > 57/3
x > 19
x + 1
19 + 1
20
x + 2
19 + 2
21
