What is the approximate area of the circle shown below?
2 answers:
Answer: The correct option is D.
Explanation:
From the given figure it is noticed that the point C is the center of the circle and the length of the diameter is 18 cm.
We know the diameter is twice of the radius,
Therefore, the radius of the circle is 9 cm.
The formula to find the area of the circle is,
Therefore, the D is the correct option. The area of the circle is 254 cm square.

Let's assume
boiling point is y
altitude is x
we are given
This relationship between altitude and boiling point is linear
At an altitude of 1000 feet, water boils at 210°F
so, first point is (1000,210)
so, x1=1000 , y1=210
At an altitude of 3000 feet, water boils at 206°F
so, second point is (3000,206)
so, x2=3000,y2=206
now, we can find slope
now, we can plug values
now, we can use point slope form of line
so, we can plug it
so, point slope form of line is
now, we can plug x=8000
and then we can solve for y
So,
the boiling point of water at an altitude of 8000 feet is 196°F..........Answer

Answer:
<h2>Option A = 1*3 = 3 unit² </h2>F = (3,7)
G = (6,4)
H = (5,3)
E= (2,6)
= (3 units)
<h3>Distance between FE = GH </h3>= 1 units
Area = 3* 1
= 3 units²
