What is the approximate area, in square units, of the circle below

A)50

B)32

C)64

A) 50

Attached is the image of the figure.

Step-by-step explanation:

Area of a circle can be expressed as;

Area A = πr^2 ......1

Where;

r = radius

From the attached image, the shape is a Circle and the diameter of the circle is 8 units.

Diameter d = 8

Radius r = diameter/2 = 8/2 = 4 units

Substituting the radius into equation 1;

Area A = π × 4^2 = 16π

Area A = 50.265

Area A = 50 square units (approximately)

idk

step-by-step explanation:

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
