A Spherical Stone In The Courtyard Of The National Museum Of Costa Rica Has Thediameter Of About 8 Feet.

Answers

Answer 1
B) 6,839 cubic feet

Analiese,
The formula for volume of a cylinder is v=πr^2h
So first you plug in the info. you were given.
v=3.14x11^2x 18
Then, you simplify the equation.
v=3.14x121x18
v=3.14x2,178
v=6,839 cubic feet
Hope this helped
Answer 2
B. 85.3 r cubic feet

Answers

-4(x-1)=-3x+13-9-x
-4x+4=-3x+4-x
-4x+4=-4x+4
-4x=-4x
0=0

Answer:

x can be any real number.

Step-by-step explanation:

- 4 (x - 1) = - 3x + 13 - 9 - x

The easiest approach to solving this problem is to simplify each side. Start by focusing on the left side, distribute the term outside of the parenthesis, multiply every term inside the parenthsis by the term outside of it,

- 4 ( x - 1 ) = - 3x + 13 - 9 - x

Distribute,

(-4)(x) + (-4)(-1) = - 3x + 13 - 9 - x

Simplify,

-4x + 4 = - 3x + 13 - 9 - x

Simplify the right side of the equation, combine like terms,

-4x + 4 = - 3x + 13 - 9 - x

Rearrage,

-4x + 4 = -3x - x + 13 - 9

Simplify,

-4x + 4 = -4x + 4

At this point, one should use inverse operations to solve the problem, but the given equation is an identity, meaning that any real value can be substituted into the parameter (x), and the equation will yield a true result. Thus, (x) equals all real numbers.

What is the measure of ∠KMN?
A. 29 degrees
B. 66 degrees
C. 53 degrees
D. 89 degrees

Answers

Answer:

  ∠KMN = 66°

Step-by-step explanation:

In ΔKMN,

∠MKN + ∠KNM + ∠KMN = 180       {Angle sum property of triangle}

39 + 75 + ∠KMN = 180

       114 + ∠KMN = 180

               ∠KMN = 180 - 114

           ∠KMN = 66°

Answer:

B) 66

Step-by-step explanation:

Step-by-step explanation:

45x = 180°

divide both sides of the equation by 45:

x = 4°
