Original Circle Area = 45

A = pi * r^2

Plug in what we know:

45 = 3.14 * r^2

Divide 3.14 to both sides:

14.3312102 = r^2

Find the square root of both sides:

r = 3.78565849

Find 2/3 of this:

2/3 * 3.78565849 = 2.52377233

So this is the radius of the newly dilated circle.

A = pi * r^2

A = 3.14 * 2.52377233^2

A = 3.14 * 6.36942677

A = 20

So the area of the newly dilated circle is 20 square inches.

Leya [2.2K]

Answer:

  θ = {(4/3 +2k)π, (5/3 +2k)π}

Step-by-step explanation:

From your knowledge of trig functions, you know that sin(60°) = sin(π/3) = (√3)/2. So, the angles of interest are in the 3rd- and 4th-quadrant and will have π/3 as their reference angle.

  θ = 4/3π +2kπ, and 5/3π +2kπ
