A nail has a circular head with a diameter of 0.40 centimeters.
What is the area of the nail's head, rounded to the nearest hundredth of a square centimeter?

Answers

Answer 1
π r^2 is the formula for area of a circle. So take half the diameter, which is 0.20, and plug that in for r. Your answer will be 0.4π or ≈1.2566

What are the factors of -24 that have a sum of 5?

Answers

Answer:

Step-by-step explanation:

5 Easy as 1-2-3

5 is a prime number.

Prime factorization: 5 is prime.

The exponent of prime number 5 is 1. Adding 1 to that exponent we get (1 + 1) = 2. Therefore 5 has exactly 2 factors.

Factors of 5: 1, 5.

Factor pairs: 5 = 1 x 5.

5 has no square factors that allow its square root to be simplified. √5 ≈ 2.236.

To find:

The value of x.

Solution:

According to the exterior angle theorem, the exterior angle of a triangle is equal to the sum of two opposite interior angles.

In triangle ABC, using exterior angle theorem, we get

[tex]\angle ACD=\angle ABC+\angle BAC[/tex]

[tex]x=75^\circ +30^\circ [/tex]

[tex]x=105^\circ [/tex]

The value of x is 105 degrees.

Therefore, the correct option is C.
