Find the area and thhe circumference of a circle round your anser to the nearest hundredth if the diameter is 6
1 answer:
---------------------------------------------------------------------------------------------- Find Radius ---------------------------------------------------------------------------------------------- Radius = Diameter ÷ 2 Radius = 6 ÷ 2 Radius = 3 units ---------------------------------------------------------------------------------------------- Find Area ---------------------------------------------------------------------------------------------- Area = πr² Area = π (3)² Area = 28.27 units² (Nearest hundredth) ---------------------------------------------------------------------------------------------- Find Circumference ---------------------------------------------------------------------------------------------- Circumference = πD Circumference = π(6) Circumference = 18.85 units (Nearest hundredth) ----------------------------------------------------------------------------------------------Answer: Area = 28.27 units² ; Circumference = 18.85 units ----------------------------------------------------------------------------------------------

Step-by-step explanation:
The value of k must be restricted from being one that makes the original denominator zero. Hence k ≠ -1 or 5 .
- 18 2- 20 = -18 Because you do the same thing just going to end up with a negative.
What those cm represent you just have to apply the formula if H=6cm W=2 L=3 surface=2(wL +L*H+W*H) =2(2*3+3*6+2*6) =2*36=72 u^2
38-36 =2
36-30 = 6
30-28 = 2
28-22 = 6
so next number would be 22-2 = 20
next number = 20
