The radius of a semicircle is 3 kilometres. What is the semicircle's perimeter?
alina1380 [7]

Answer:

In terms of Pi: 3\pi + 6 km

Exact value (rounded): 15.42477 km

Approximated (3.14): 15.42 km

Step-by-step explanation:

Hello!

A semicircle's perimeter can be found using the formula: P = \pi r + 2r

We can plug in the values to solve for the perimeter.

<h3>Solve</h3>
  • P = \pi r + 2r
  • P = \pi(3)+ 2(3)
  • P = 3\pi + 6

In terms of Pi, it is 3\pi + 6,

Exact value of Pi, it is 15.42477

Approximation of Pi (3.14), it is = 15.42

Need help with thisssssss
Naddika [18.5K]

Answer:

see explanation

Step-by-step explanation:

The perimeter of a rectangle = 2l + 2w ( l is length and w is width )

given w = 63, then

2l + (2 × 63) = 324

2l + 126 = 324 ( subtract 126 from both sides )

2l = 198 ( divide both sides by 2 )

l = 99 m ← length of garden

-----------------------------------------------------------------

The area of a rectangle = lw ( l is length and w is width )

given l = 94, then

94w = 5828 ( divide both sides by 94 )

w = 62 cm ← width of window

Can somebody explain to me how to do this and the answers and how you got it
yaroslaw [1]
7. Easiest method is substitution.  Since y=x/2, then:
2x+3(x/2)=28
8.Substituting again, we get:
3x-6x=6
-3x=6
x=-2
(-2,6)

The measure of angle 3 is 42°<br> What is the measure of angle 1 in degrees
OlgaM077 [116]

Answer:

48 degrees

Step-by-step explanation:

Angle 2 is a right angle.

Right angles are 90 degrees.

A line is 180 degrees.

Angle 1, 5, and 2 form a line.

180-90=90

That means that Angles 1 and 5 add up to 90 degrees.

We know that Angle 3 is 42 degrees.

Angle 3 and 5 are Vertical angles.

Vertical angles are always congruent.

This means that Angle 5 is also 42 degrees.

As we discussed earlier, Angles 1 and 5 are complementary. (Add up to 90 degrees)

42+x=90

Subtract 42 from both sides.

x=48

m<1=48
