Step-by-step explanation:
The formula to find the area of a circle: 
, where 
is the radius.
The formula to find the circumference (perimeter) of a circle: 
, where is the radius.
1) To find the circumference of the circle, we need to find the radius () first. Since the area of the circle is given to us, we need to equate this to the formula to find the area of a circle.
Cancel the 
by bringing it to the other side.
÷
2) Find the circumference of the circle by using the formula, .

The slope of the line is 1
Answer:
124.8 Inches
Step-By-Step
1/2 0.835 Inches = 0.4175
r = 0.4175
h = 0.077
A=2πrh+2πr^2
A=2π(0.4175)(0.077)+2π(0.4175^2)
A = 3.12
Nickel = 5 Cents
$2 = 200 Cents
200 / 5 = 40
(3.12)(40) = 124.8 In

Answer:
∠6 = 80°
Step-by-step explanation:
∠5 and ∠6 form a straight angle and are supplementary, hence
∠5 + ∠6 = 180 ← ∠5 = 100° ( given ), hence
100 + ∠6 = 180 ( subtract 100 from both sides )
∠6 = 80°
