Find Diameter :
---------------------------------------------
Circumference = πD
πD = 12π
D = 12
---------------------------------------------
Find Radius :
---------------------------------------------
Radius = Diameter ÷ 2
Radius = 12 ÷ 2
Radius = 6
---------------------------------------------
Find Area :
---------------------------------------------
Area = πr²
Area = π(6)²
Area = 36π or 113.10 units² (nearest hundredth)
---------------------------------------------
Answer: Area = 113.10 unit²

Answer:
x = 6.2
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opp / adj
tan 32 = x/ 10
10 tan 32 = x
x=6.24869
Rounding to the nearest tenth
x = 6.2
Answer:
122
Step-by-step explanation:
x = 180-(180-50-72) = 180-(130 - 72) = 180 - 130 + 72 = 50 + 72 = 122
Imagine it like a piece of chocolate amongst three people. The one u want to break into to share among the other is the first number.
so the number of chocolate pieces ÷ by number of people
e.g: 6 pieces of chocolate ÷ 3 people
6÷2 = 3
however you can also divide the other way round. by dividing the smaller number first. this means u are diving a small amount to even smaller amounts.
2÷4 = 1/2
