Which of the following doesn't belong?
64, 16, 36, 32, 8, 4
i don't understand this at brain is like everywhere today

36 does not belong in that group because it is the only number that is not a power of 2:

2^2 OR 2 x 2 = 4
2^3 OR 2 x 2 x 2 = 8
2^4 OR 2 x 2 x 2 x 2 = 16
2^5 OR 2 x 2 x 2 x 2 x 2= 32
2^6 OR 2 x 2 x 2 x 2 x 2 x 2= 64

The area of circle is 78.5 units².

Step-by-step explanation:

Area of the circle is defined by the formula A = π r²

Here r = radius of the circle and value of π = 3.14

Now by putting these values in the formula  we can get area of the circle.

A = (3.14) × 5²

A = 3.14 × 25

A = 78.5 units²

The area of circle is 78.5 units²
