#### Number of problems found: 343

- Area of a rectangle

Calculate a rectangle area with a diagonal of u = 12.5cm and a width of b = 3.5cm. Use the Pythagorean theorem. - The rotating

The rotating cone has a height of 0.9 m and the diameter of the base is 7.2 dm. Calculate the surface of the cone. (Hint: use Pythagorean theorem for a side of cone) - Annular area

The square with side a = 1 is inscribed and circumscribed by circles. Find the annular area. - Diamond area from diagonals

In the diamond ABCD is AB = 4 dm and the length of the diagonal is 6.4 dm long. What is the area of the diamond? - Is right triangle or not

If right triangle ABC, have sides a=13, b=11.5, c=22.5. Find area. - Diagonal to area

Calculate the area of a rectangle in which the length of the diagonal is 10 cm. - Inscribed rectangle

The circle area is 216. Determine the area of inscribed rectangle with one side 5 long. - Circles

The area of a circle inscribed in a square is 14. What is the area of a circle circumscribed around a square? - Hexagon area

The center of the regular hexagon is 21 cm away from its side. Calculate the hexagon side and its area. - Triangle

Calculate the triangle sides if its area S = 630 and the second cathetus is shorter by 17. - Flakes

We describe a circle of the square, and we describe a semicircle above each side of the square. This created 4 flakes. Which is bigger: the area of the central square, or the area of four flakes? - Circular ring

Square with area 16 centimeters square are inscribed circle k1 and described circle k2. Calculate the area of circular ring, which circles k1, k2 form. - Rhombus

The rhombus with area 68 has one diagonal is longer by 6 than second one. Calculate the length of the diagonals and rhombus sides. - Waste

How many percents are waste from a circular plate with a radius of 1 m from which we cut a square with the highest area? - Leg

Determine the trapezoid area with bases 71 and 42, and the height is 4 shorter than its leg. - The perimeter

The perimeter of equilateral △PQR is 12. The perimeter of regular hexagon STUVWX is also 12. What is the ratio of the area of △PQR to the area of STUVWX? - Area of the cone

Calculate the surface area of the cone, you know the base diameter 25 cm and a height 40 cm. - Equilateral triangle

Calculate the area of an equilateral triangle with circumference 72cm. - Equilateral triangle vs circle

Find the area of an equilateral triangle inscribed in a circle of radius r = 9 cm. What percentage of the circle area does it occupy? - Lateral surface area

The ratio of the area of the base of the rotary cone to its lateral surface area is 3: 5. Calculate the surface and volume of the cone, if its height v = 4 cm.
