Ahaha… I’m really not good at geometry. I get basic stuff, but I really don’t get this once The full problem is "Prove that the area of a circle circumscribed about a square is twice the area of the circle inscribed within the square"
Let s = the length of the side of a square.
Then the [...]
The radius of a circle I is one half the radius of circle ll. What is the ratio of the area of circle l to the area of circle ll?
Let’s say circle I has radius of 1 and circle II has a radius of 2. Find the areas:
circle I = π * 1² = π [...]
The area of the square is 196cm squared. The area of the circle is 153.94cm squared. I need to know how to calculate what fraction the area of the circle is of the area of the square.
Help ?
Calculate the square root of the area of the square.
square root of 196 = 14.
divide that by two [...]
How do you figure out the area of a circle?
If the radius is 7cm then obviously the diameter is 14cm. But I can’t remember to figure out the area of a circle. is it 7*14=98 ?
Area = πr^2
Area = 3.1416(7)^2
Area = 3.1416(49)
Area = 153.93804 sqcm
How fast is the area of a circle increasing when the circumference equals 8 feet and the circumference is increasing at a rate of 7 feet per minute? The area is increasing at ? square feet per minute.
Thanks in advance for the help!
C = 2pi*r
A = pi*(C / 2pi)^2
A = C^2 / 4pi

What is the diameter of a circle with an area of 81p in2?
4.5 inches
9 inches
18 inches
40.5 inches
By 81 p in2, I assume you mean 81*pi in^2
A = pi * r^2
81*pi in^2 = pi r^2
81 in^2 = r^2
Take the square root of both sides to get
9 in = r
Since the diameter is [...]
The radius of 32mm and asks for area, and unsure with a circle, thanks!
A = r^2 * pi
32^2 * pi = approx 3217 mm^2
The only thing you know is the length of a side is 14 cm. PLEASE HELP!
also, could you find the area of the part not included in the circle?
Draw the radius of the circle from the bottom middle of the triangle to the circle’s center. Then draw a line from the circle’s center to the [...]
k, i have to find the circumference, diameter and radius for a quarter circle with an area of 19.93. im sorry, i usually figure these out myself, but im so stuck on this one:( any help would be appreciated. thnx<3
A=pi r^2, so knowing that you can figure out what the radius is by reworking the [...]
it is not the mange, we bath him by weekly, hes well groomed, but he acts like that area hurts, he bites at the area.
You did not say what color your Doberman is.
If it is a Fawn or a Blue, then it could be suffering from color dilution alopecia.
If its a Black or a red [...]
