A conduit has a cross-section of 54 mm². Is it possible to fit 6 conductors each with a cross-section of 6.7 mm² inside it? - Wheat
A rectangular field with dimensions 529 m × 1001 m yielded 2780 quintals of wheat last year (1 quintal = 100 kg). During the year, a pipe had to be repaired, which meant that a strip 4 m wide parallel to the side of length 1001 m could not be used for gro - Expansion
If one side of a rectangle is multiplied by 2 and the other side by 4, by what percentage does the area increase? - Floor
A room has a floor area of 33 m² and a width of 4 m. What is the perimeter of the room as shown on a map at scale 1:75, measured in centimetres? - Garden
A garden has two opposite parallel fences separated by a distance of 39.7 m. The lengths of these two fences are 73.2 m and 63.6 m. Calculate the area of this garden. - Rectangle
In a rectangle with sides 8 and 9, a diagonal is drawn. What is the probability that a randomly selected point inside the rectangle is closer to the diagonal than to any side of the rectangle? - Map
A forest has an area of 77 ha. What area does it occupy on a map at scale 1:10000? - Wire
Each pass of a wire through a drawing die reduces its diameter by 13%. What will the diameter of a wire be after 6 passes, if it starts with a diameter of 6 mm? - The pipeline
How long is a pipe with an outer diameter of 1.4 m if painting it consumed 35 kg of paint? One kilogram of paint covers 9 m². - Area
Calculate: x = 8 m² + 8 dm² + 8 cm² - Cube
Calculate the surface cube with edge 11 dm. - Cable
A cable consists of 5 strands, each strand made up of 11 wires with a diameter of d = 0.3 mm. Calculate the total cross-sectional area of the cable. - Pipeline
By what percentage does the cross-sectional area of a pipe decrease if the circular cross-section is replaced by a square with the same perimeter? - Circles 2
Calculate the area of the region between the circumscribed circle and the inscribed circle of a triangle with sides 29 cm, 16 cm, and 21 cm. - Arc and segment
Calculate the length of circular arc l, the area of the circular arc S1, and the area of circular segment S2. The circle's radius is 88, and the corresponding angle is (4)/(7) π. - Square
Calculate the area of a square with diagonal 17 cm. - Sphere
A sphere has a surface area of 21000 cm² and a mass of 73.2 kg. What is its density? - Rectangular field
One dimension of a rectangular field is 168 m greater than the other. When each side is increased by 9 m, the area of the field becomes 2187 m². Find the dimensions of the field. - Center traverse
Does the midsegment of a triangle bisect its area? - Diagonals of the rhombus
Calculate the height of a rhombus whose diagonals are 18 cm and 6 cm.
