Mathematics

Step-by-step explanation:

Total distance covered in 200 rotation = 440 m

Distance covered in 1 rotation

= 440 / 200

= 2.2 m

Distance covered in 1 rotation = Circumference of circle so

circumference = 2πr

2.2 = 2 * 22/7 * r

2.2 = 6.28 r

r = 2.2 / 6.28

r = 0.35 m

Now Area of the wheel

= πr²

= 22 /7 * 0.35 * 0.35

= 0.385 m²

Hope it will help :)❤

Step-by-step explanation:

A pyramid with a triangle-shaped base whose three triangular faces meet at the ap/ex. The triangular pyramid formula included both the volume and surface area of the pyramid. The triangular pyramid volume formula calculates the base area and the height whereas the surface area of the triangular pyramid calculates the base area, perimeter,, and slant height. Formulas for volume and surface area of the triangular pyramid are given below that are used in the triangular pyramid formula: 

Volume= 1/3 × Base area × Height

Consider
.. X = {1, 2, 3, 4}, x = 4
.. Y = {2, 3, 4, 5, 6}, y = 5, w = 3
The elements in X or Y (X ∪ Y) are {1, 2, 3, 4, 5, 6}, n = 6.
.. n = 6 = 4 + 5 - 3

Note that if we just add x and y, we count the common elements twice. In order to just count the common elements once, we need to subtract that count from the total of x and y.

selection B is appropriate.
