Answer:
$367.38 is the cost to stain the entire deck.
Step-by-step explanation:
Here is what you need to know beforehand:
<em>Diameter</em> is <u>a line</u> that goes <u>through a circle</u>. <em>Radius</em> is <u>a line </u>that goes from <u>the edge of the circle all the way to the center</u>/<u>a line </u>that goes <u>halfway through the circle</u>.
--------------------------------------------------------------------------------------------------------------
<u>First, find the area of the circle. Here is the formula:</u>
Area = 3.14 (Pi) x r²
Since radius is half of the diameter (as explained above), you'll need to divide the diameter in half: 12m/2 = 6m
So the formula will look like this:
Area = 3.14 x 6²
<u>Then, you just do the math:</u>
Area = 3.14 x 6²
Area = 3.14 x 36
Area = 113.04
The goal of the problem is to find the amount of money Emma needs. <u>Finally, all you need to do is multiply the amount it cost to stain per square meter by the total area of the deck:</u>
Answer = 113.04 x 3.25
Answer = 367.38
$367.38 is the cost to stain the entire deck.
Question isnt well formatted :
Answer:
1 : 6
Step-by-step explanation:
Given the question :
3x = 1/2y
3x = y/2
Multiply both sides by 2
3x * 2 = y/2 * 2
6x = y
This can be interpreted as :
y = 6 times the value of x
x = y/6
x : y
1 : 6
A. Length - 100 ft Width - 50 ft is the measurement of Tony's backyard.
Albert's Perimeter = 2(l+w) = 2(40+20) = 2(60) = 120 ft.
Tony's Perimeter = 120 ft * 2.5 = 300 ft
Tony's length = 40 ft * 2.5 = 100 ft
Tony's widht = 20 ft * 2.5 = 50 ft
To check tony's perimeter:
P = 2(l + w) = 2 (100 + 50) = 2 (150) = 300 ft.
Cot^2x - cot^2x cos^2x
= cot^2x - {(cot^2x)(cos^2x)}
= cot^2x { 1 - cos^2x }
= cot^2x { sin^2x }
= (cos^2x/sin^2x) { sin^2x }
= cos^2x
