Answer:
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)
The 2 angles given are vertical angles, which mean they are the same.
So we have: 3x +1 = 64
Subtract 1 from each side:
3x = 63
Divide both sides by 3:
X = 63 / 3
X = 21
The answer is A.
Answer:

Negative numbers go first, the greater the number, the smaller the number.
