How big is the area of the circular cutout described by the minute hand 14 cm long in 40 minutes? - 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 21273

The dragon has the shape of a circular section with a central angle of 40 ° and a radius of 35 cm. How much paper do we need to make if 10% is added to the curved ones? - Mice

Mice consumed a circular hole in a slice of cheese. The cheese has the shape of a circular cut with a radius of 20 cm and an angle of 90 degrees. What percentage of the cheese ate mice if they made 20 holes with a diameter of 2 cm? - Three segments

The circle is divided into 3 segments. Segment A occupies 1/4 of the area. Segment B occupies 1/3 of the area. What part is occupied by section C? In what proportion are areas A: B: C? - Quarter of a circle

Calculate the circumference of a quarter circle if its area is S = 314 cm². - Irrigation sprinkler

The irrigation sprinkler can twist with an angle of 320° and has a reach of 12 meters. Which area can irrigate? - Equilateral triangle v3

Find the area of the colored gray part. An equilateral triangle has a side length of 8 cm. Arc centers are the vertices of a triangle. - Math heart

A stylized heart shape is created from a square with a side of 5 cm and two semicircles over his sides. Calculate the area and its circumference. - Arc

What area of a circle occupied the flowers planted in the arc of a circle with radius 3 m with central angle 45°? - Circle sector

The circular sector with a central angle 160° has an area 452 cm². Calculate its radius r. - Field with vegetables

Field planted with vegetables has a rectangular isosceles triangle with a leg length of 24 m. At the triangle's vertices are positioned rotating sprinklers with a range of 12 m. How much of the field sprinkler doesn't irrigated? - Goat and circles

What is the radius of a circle centered on the other circle and the intersection of the two circles is equal to half the area of the first circle? This task is the mathematical expression of the role of agriculture. The farmer has circular land on which g - Park
