No. Area of a circle equals pi times the radius squared. That means multiply the radius times itself. For example, if the radius is 3, the area = π x 3 x 3 = 9π
Apply the standard equation of a circle with center at (h,k) and radius r:
(x-h)^2 + (y-k)^2 = r^2
Using the given data,
(x-2)^2 + (y+4)^2 = 3^2

The required "option B) 60°" is correct.</h2>
Step-by-step explanation:
In question figure,
∠ YUV = 40°, ∠ XUY = 105° and ∠WUX = 155°
To find, the value of ∠ VUW = ?
We know that,
The circle having 360°
∴ ∠ VUW + ∠ YUV + ∠ XUY + ∠WUX = 360°
⇒ ∠ VUW + 40° + 105°+ 155° = 360°
⇒ ∠ VUW + 300° = 360°
⇒ ∠ VUW = 360° - 300°
⇒ ∠ VUW = 60°
∴ The value of ∠ VUW = 60°
Hence, the required "option B) 60°" is correct.
