The equation of the circle:
( x - h )² + ( y - k )² = r²;
h = - 2, k = 5, r = 4
Answer:
A ) ( x + 2 )² + ( y - 5 )² = 16
Answer: A 45-degree angle is exactly half of a 90-degree angle formed between two rays. It is an acute angle and two angles measuring 45 degrees from a right angle or a 90-degree angle. We know that an angle is formed when two rays meet at a vertex.

Answer:
3 In²
Step-by-step explanation:
Talking about surface area, the total area of an object is taken into consideration.
NB: Kindly check the attached picture for the diagram of the 3D object.
In this question, the surface area has to be determined and we will have to take into consideration all the area of the 3D object given in the question.
Surface Area = 6 × k².
Surface area = 6 × ( 1.8 × 1.8) cm².
Surface Area = 19.44 cm².
The next thing to do here is to convert the cm² to in². Therefore, 19.44 cm² ------> x in².
19.44 × 0.155 in² = 3 in².
