number of decimal places from 0 to 8. So, you can set up the calculator to round decimal numbers to tenths, hundredths, thousandths etc. By default, the app shows 2 decimal places. If you need to round the result to the nearest whole number, just set the number of decimal places to ...
PI is approximately 3.14, by definition, the number of times that a circle's diameter will fit around the circle. PI goes on forever, and can't be calculated to perfect precision, although you can do better than 2 decimal places. On our site and in all of our calculators, 3.14159 is ...
The value of pi (π) is approximately 3.14159, but it is an irrational number, which means that it cannot be expressed exactly as a fraction. The decimal representation of pi goes on indefinitely, and it has been calculated to millions of decimal places. How do you find the product of se...
If a single decimal digit is enough, the ratio 25/8=3.12525/8=3.125 will be enough for you. This one is easy to calculate! The first approximation that shows us the most famous approximation of pi, 3.143.14, is 22/722/7. We owe this one to Archimedes (the "Eureka" guy), that al...

Find the area of the sector below, giving your answer to 1 decimal places. The sector has a central angle of 278° and a radius of 9.6 cm. The area of a sector: \[ A = {\theta \over 360} \pi r^2 \] where A is the area, θ is the central angle and r is the radius of...
The angle φφ is measured from the X-axis counterclockwise, and it can vary from 00 to 2π2π or from −π−π to ππ (depending on convention since both are equivalent). Knowing that we can write any complex number using its polar coordinates on that plane: a=∣z∣⋅cos...
