Answer:1384.74 square inches
Step-by-step explanation:
Diameter=42 inches
Radius=42/2
Radius=21 inches
π=3.14
area of circle=π x radius x radius
Area of circle=3.14 x 21 x 21
Area of circle=1384.74 square inches
The inscribed polygon can be square or a hexagon.
<h3>What is polygon'?</h3>
A polygon is a two-dimensional geometric figure that has a finite number of sides. The sides of a polygon are made of straight line segments connected to each other end to end.
First,
if we join A to B, B to C, C to D and D to A then a square will be formed.
But, if we join passing through the arc intersecting point then join to B then again join to a line passing through arc intersecting then to D.
A six side figure will obtain named as hexagon.

Alright so you need to put this equation in slope-intercept form. So you flip the x across the = sign and switch the sign to get 6y=-x+8.
Then you need y by itself so you divide everything by 6. Which gets you y=-1/6x+8/6.
Now simplify
y=-1/6x+4/3 or y=-1/6x+.75
(4/3 =.75)
Answer:
9:18
Step-by-step explanation:
1:2 means that you have to multiply the first number by 2 to get the second number. Therefore, you have to multiply 9 by 2, which is equal to 18. Therefore, it would be 9:18.

Formula
--------------------------------------------------
Area of circle = πr²
--------------------------------------------------
Find radius
--------------------------------------------------
πr² = 75
r² = 75 ÷ π
r² = 23.87
r = √23.87
r = 4.89 cm (nearest hundreds)
--------------------------------------------------
Answer : radius = 4.89cm
