Find the perimeter of the window. Round your answer to the nearest tenth.
liberstina [14]
1) The perimeter is the sum of the lengths of the straight edge (the diameter of the semicircle) and the length of the arc of the semicircle.

The circumference of a 4 ft circle is
  π*diameter = π*4 ft ≈ 12.566 ft
The semicircle will have a length that is half that, 6.283 ft. When this length is added to the diameter, the perimeter is found to be
  Perimeter = 4 ft + 6.283 ft ≈ 10.3 ft.


2) The area of a circle is given by the formula
  A = (π/4)d²
For a diameter of 15 inches, the area is
  A = (π/4)(15 in)² = 56.25π in²
  A ≈ 176.7146 in²

The area of the circle is about 176.71 in².

You want to test the effect of light on the distribution of Artemia in your 35cm long testing chamber. If you measure the light
Dvinal [7]

Answer:

64.3 lumens

Step-by-step explanation:

Data provided in the question:

Length of the testing chamber = 35 cm

Light at one end = 10 lumens

Light at other end = 200 lumens

now,

since the variation is linear,

therefore, the gradient of the variation

= \frac{200-10}{35}

= 5.43

also,

the darkest end is the end with 10 lumens

therefore,

The lumens at 10 cm from the darkest end

= 10 + 5.43(10)

= 10 + 54.3

= 64.3 lumens
