If you have the radius, then area = pi*r2 which you then round to the nearest hundredth.
If you do not know the radius but do know the diameter or circumference, you can calculate the radius. Otherwise you need to measure it.
all you do is find the area of the circle... if you mean find the squares area, find the area of the circle, and then the square's area and subtract the squares area to the circles area
You find the area of the whole square first. Then you find the area of the circle inside of it And then subtract the area of the circle from the area of the square and then you get the shaded area of the square
The area of a circle is π (Pi) times the Radius squared.
The area of a circle can be found with the formula (pi)r^2
To find the circumference of a circle then multiply pi (3.14159265...) by the diameter of the circle. To find the area then multiply pi by the radius squared.
A circle with a diameter of 11 inches has an area of 95.03 square inches.

16.6 x pi = 52.15 to the nearest hundredth
50.27 yards
to find the raduis of any circle, divde the diameter by 2. in this case, the answer would be 3.50
pi r2 h is 38.5. pir2 is the area of the base, so this is 38.5/6, is 6.42cm2
For circumference, multiply the diameter by pi and round the product to the second decimal place. For area, multiply the square of the radius by pi and round the product to the second decimal place.
First find the length of the other leg by using Pythagoras: 112-42 = 105 Area = (4*the square root of 105)*1/2 = 20.49390153 Area = 20.49 square cm to the nearest hundredth
To find the height of a parallelogram, you divide the area by the base length. So in this case, the height of the parallelogram would be 115/12 = 9.58 to the nearest hundredth.

Oh, dude, measuring stuff, huh? So, like, if you wanna round 96.3cm to the nearest tenth, you just look at that third decimal place. Since it's 3, which is less than 5, you keep the 9 the same, and you get 96.3cm. Easy peasy, lemon squeezy!
The answer depends on what the number 0.45 refers to: radius, diameter or area?
