- Right triangle
The legs of the right triangle are in the ratio a:b = 2:8. The hypotenuse has a length of 87 cm. Calculate the perimeter and area of the triangle. - Geometric mean
Calculate the geometric mean of numbers a=15.2 and b=25.6. Determine the mean by construction where a and b are the length of the lines. - Magnification of the square
If we increase the square side, increase the area of the 70 %. About what percentage was increased on its side? - Cube wall
The surface of the first cube wall is 64 m². The second cube area is 40% of the surface of the first cube. Find the length of the edge of the second cube (x).
- Circle chord
What is the length x of the chord circle of diameter 115 m if the distance from the center circle is 11 m? - Square diagonal
Calculate the length of the square diagonal if the perimeter is 172 cm. - Cube diagonal
Determine the length of the cube diagonal with edge 23 km. - Sandpile
Auto sprinkled with sand to an approximately conical shape. Workers wanted to determine the volume (amount of sand) and therefore measure the base's circumference and the length of both sides of the cone (over the top). What is the sand cone's volume if t - Trolleybus
