Use the Law of Pythagoras - in this case, the answer is the square root of (162 + 92).
Diagonal = sqrt(36 + 25) ie sqrt 61 which is 7.8 inchesto the nearest tenth.
You can measure it. Or you can measure some other quantities (for examples, the lengths of the sides of a triangle), and calculate the angle using trigonometry.
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.

If cos y = 0.5135 then y = 59.1°.
I can and will. So if you put the diagonal through a rectangle you create a right angled triangle of which you can use pythagoras theorem. x2 = 152 + 62 x2= 261 x = 16.16m
Use Pythagoras' theorem: 1272+76.22 = 21935.44 and the square root of this is 148.1061781 Answer: 148 to the nearest cm
The diagonal creates a right angled triangle with one pair of long and short sides - the diagonal is the hypotenuse. We know the angle between the long side (adjacent) and hypotenuse as 42.6°; We want to find the length of the short (width) side (opposite). We can use the Tan ratio: tan = opposite/adjacent → opposite = adjacent × tan → width = 26.63 in × tan 42.6° = 24.487... in → width is 24.5 inches to the nearest tenth of an inch.
The diagonal of a square is usually found using Pythagoras's theorem, a2 + b2 = c2. Since this is a square, a = b; thus: c2 = 2s2, where s is the side length and c is the diagonal. s = square root(c2/2) = square root(625/2) = square root(312.5) = 17.8in The dimensions of a square whose diagonal is 25inches is 17.8in x 17.8in (rounded to the nearest tenth)
The area of the WHOLE rectangle is less than 0.01 sq metres. So it is a lot less than a cent (which is 40 metres2 ). So to the nearest tenth of a cent, the area of the circle, which will be smaller than that of the rectangle, is 0. No calculations required.
South Dakota.----Many have a rough shape of a rectangle, but Wyoming and Colorado seem to be nearest to a true rectangle.
42 cm
Let the length be (4x+1) and the width be x: length*width = area (4x+1)*x = 97 4x2+x-97 = 0 Solving the above quadratic equation works out as: x = -5.051015124 or x = 4.801015124 it must be the latter because dimensions can't be negative. Therefore: length = 20.2 cm and width = 4.8 cm
Draw a diagonal line across the rectangle. The resulting two right triangles will each have identical areas half that of the rectangle. The area of the rectangle is its height x base, and the area of each of the two triangles is 1/2 of its height x base.
Oh, what a delightful question! A quadrangle is a four-sided shape, like a square or rectangle. To find the nearest half inch, you simply measure the side lengths of the quadrangle and round to the nearest half inch. Remember, there are no mistakes in art, only happy little accidents!
you need an object to measure to determine the nearest inch
The diagonal of a rectangle can be calculated using the Pythagorean theorem, which is a^2 + b^2 = c^2. In this case, a = 40 cm, b = 50 cm. So, c^2 = 40^2 + 50^2 = 1600 + 2500 = 4100. Taking the square root of 4100 gives us the diagonal, which is approximately 64 centimeters.
