How to find the circumference of a circle

Mathematics
1 answer:
wlad13 [49]3 years ago
7 0
C = 2pi(r). Find the radius of the circle first. Then multiply that by 2pi. 
Pi=3.14159... 2pi = 2 x 3.14159...
Therefore C = 2 x 3.14159... x r

Find the measures of the angles of an isosceles triangle with a vertex angle of 42 degrees
I am Lyosha [343]

Answer:

69°, 69°, and 42°

Step-by-step explanation:

Isosceles triangles have three angles -- one vertex angle and two base angles.

The <u>base angles have the same measure</u> and the vertex angle has a different measure.

<u>Remember all triangles' interior angles sum to 180°.</u>

If the vertex angle is 42°, then the two base angles combined are:

180° - 42° = 138°

Since the base angles are the same, <u>each base angle is:</u>

138° ÷ 2 = 69°

Therefore the angles in the triangle measure 69°, 69°, and 42°.

Solve each radical equation. Be sure to check your solutionsa)√(2x-3)=11b)∛(6-x)=-3
leva [86]

Answer:

a) x = 62

b) x = 33

Step-by-step explanation:

Hi there!

a) Let´s write the equation:

√(2x-3) = 11

Square both sides

2x - 3 = 121

add 3 to both sides of the equation

2x = 124

divide by 2 both sides

x = 62

Let´s check:

√(2x-3) = 11

x = 62

√(2(62)-3) = 11

√(124-3) = 11

√121 = 11

11 = 11

x = 62 satisfies the equation

b) Let´s write the equation:

∛(6 - x) = -3

Cube both sides

6 - x = -27

subtract 6 to both sides

-x = -27 - 6

-x = -33

divide by -1 both sides

x = 33

Now, let´s check the result:

∛(6 - x) = -3

x = 33

∛(6 - 33) = -3

∛(-27) = -3

-3 = -3

x = 33 satisfies the equation
