Diameter of a circle = 28 m
Then, radius of the circle will be :
Thus, the radius of this circle = 14 m
Area of circle :
Thus, the area of this circle = 615.44 m²
Circumference of circle :
The circumference of this circle = 87.92 m
Therefore, the area of this circle = 615.44m² and the circumference of this circle = 87.92m
Answer: height = 17.5cm
Step-by-step explanation: Peter mixes blue and yellow paint in the ratio 2:3, which means:
x = 12.6L
The container is full with the two paints, so total volume:
V = 12.6 + 8.4
V = 21L
Knowing that 1L = 1dm³ and sides of cuboid is measure in cm:
V = 21dm³ = 21000cm³
Volume of a cuboid is calculated as:
V = width*length*height
Height of the container is
height =
height =
height = 17.5cm
The height of the container is 17.5cm.
