The radius of a semi-circle measures 5 units. Find its area.

Mathematics
1 answer:
shutvik [7]3 years ago
8 0

Answer:

≈39.27 units

Step-by-step explanation:

To find the area of a semi circle, you use the formula for finding the area of a circle, which is \pir^{2}, and then you divide that by 2 since it is half of a circle.

In this case, \pi(5)^{2} ≈ 78.54

\frac{78.54}{2} = 39.27

a long board 4.7 thick is cut into three pieces of equal length these three pieces are then stacked the stack is cut in three eq
nalin [4]

The number of pieces per stack after 3 cuts represented by a power expression can be written as 3^{3}

  • The number of equal pieces per cut = 3

  • The number of cuts made = 3

<u>Using a power </u><u>expression</u><u> </u><u>:</u>

  • The number of of equal pieces per cut is raised to a power which represents the number of cuts made

  • Thus we have number\: of \:equal\: pieces^{number\: of \:cuts}

  • After 1 cut ; 3^{1} = 3
  • After 2 cuts ; 3^{2} = 3\times3 = 9
  • After 3 cuts ; 3^{3} = 3\times3\times3 = 27

Therefore, the Number of pieces present in stack after 3 cuts is 3^{3}

Let's go through each answer choice and eliminate the choices.

a) 6(2/3) = 4, this is less than 6, making it our correct answer, but still go and check each answer
b) 6(2/3) again = 4, this is less than 6, making this answer choice wrong.
c) 6(3/2) = 9, this is greater than 6, making this answer choice wrong.
d) 6(3/3) = 6, this is equal to 6, making this answer choice wrong.

AB, CD and EF are straight lines. AB is parallel to CD. Work out the size of angle y
mylen [45]

Answer: 28

Step-by-step explanation:

Simplifying

2x + 16 = 3x + -12

Reorder the terms:

16 + 2x = 3x + -12

Reorder the terms:

16 + 2x = -12 + 3x

Solving

16 + 2x = -12 + 3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3x' to each side of the equation.

16 + 2x + -3x = -12 + 3x + -3x

Combine like terms: 2x + -3x = -1x

16 + -1x = -12 + 3x + -3x

Combine like terms: 3x + -3x = 0

16 + -1x = -12 + 0

16 + -1x = -12

Add '-16' to each side of the equation.

16 + -16 + -1x = -12 + -16

Combine like terms: 16 + -16 = 0

0 + -1x = -12 + -16

-1x = -12 + -16

Combine like terms: -12 + -16 = -28

-1x = -28

Divide each side by '-1'.

x = 28

Simplifying

x = 28
