Find the area of a square with radius of 10

Answers

Squares can’t have radius? Do you mean circle?

This formula, when properly solved, reveals that a side of the square equals half the diameter of the circle times the square root of 2. Because the area of the square is one of its sides multiplied by itself, the area equals the square of the circle's radius times 2.

Solve the triangle with the law of sines

Answers

Answer:

see below

Step-by-step explanation:

We can use the law of sines

sin 80 sin B

--------------- = -------------

31 14

Using cross products

14 sin 80 = 31 sin B

14/31 sin 80 = sin B

.984807753 = sin B

Taking the inverse sin of each side

sin ^ -1 ( .444751888) = B

26.41 = B

The sum of the angles of a triangle is 180

A+B+C = 180

80 + 26.41 + C =180

106.41 + C = 180

C = 73.59

We can use the law of sines to find c

sin 80 sin 73.59

--------------- = -------------

31 c

c sin 80 = 31 sin 73.59

c = 31 sin 73.59 / sin 80

c = 30.20

AB = 30.20

In a unit circle, ø= 90°. Identify the terminal point and sin Ø.
A. Terminal point: (0,1); sin ø= 1
B. Terminal point: (1,0); sin ø=0 C. Terminal point: (1, 0); sin ø=1
D. Terminal point: (0,1); sin ø=0

Answers

Answer:

Terminal point: (0, 1); sinФ = 1 ⇒ A

Step-by-step explanation:

In the unit circle, Ф is the angle between the terminal side and the positive part of the x-xis.

The terminal point on the positive part of the x-axis is (1, 0),which means Ф = 0° or 360° and cosФ = 1, sinФ = 0The terminal point on the positive part of the y-axis is (0, 1),which means Ф = 90° and cosФ = 0, sinФ = 1The terminal point on the negative part of the x-axis is (-1, 0),which means Ф = 180° and cosФ = -1, sinФ = 0The terminal point on the negative part of the y-axis is (0, -1),which means Ф = 270° and cosФ = 0, sinФ = -1

In a unit circle

∵ Ф = 90°

→ By using the 2nd rule above

∴ The terminal point is (0, 1)

∴ sinФ = 1

∴ Terminal point: (0, 1); sinФ = 1
