1.8 mile i think but do the math cz it should be.
b. The square is inscribed within the circle?
Answer:
a. 20π cm.
b. 20(√2)π cm,
Step-by-step explanation:
a. The diameter (d) of the circle = side of the square = 20 cm.
So the circumference = π d = 20π cm.
b. In this case the diameter = the length of the diagonal of the square.
The diagonal = diameter of the circle =sqrt ( 20^2 + 20^2) = √800 = 20√2.
So the circumference = πd = 20(√2)π.

Answer with Explanation:
It is given that infinite geometric series with a beginning value of 2 , converges to 10.
Let a be the common ratio of geometric series.Where ,a<1.
Sum to infinity of a geometric series
First four terms of geometric series
The value of cos θ is,
⇒ cos θ = 0.6
The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.
Now, We can Draw a line from point ( 0.6, 0.8 ) to the X - axis, forming a right triangle with hypotenuse = r = 1 , adjacent = 0.6, opposite = 0.8
Hence, We can formulate;
⇒ cos θ = 0.6 / 1
⇒ θ = cos ⁻¹ 0.6
⇒ θ = 53.13°
Thus, The value of cos θ is,
⇒ cos θ = 0.6
