1.6 is 20 times greater the 0.08.
Answer:
<em>The perimeter of given figure = 56.56 ft</em>
Step-by-step explanation:
<u>Step(i):-</u>
From diagram
The length of the rectangle = 10 ft
The width of the rectangle = 8 ft
Perimeter of the rectangle
= 2 ( l+w)
= 2 ( 10 + 8)
= 2 × 18
= 36
<u><em>Step(ii):-</em></u>
The semi circle is included in the given diagram
<em>Now we will find the perimeter of semicircle</em>
<em>We know that </em>
<em> perimeter of the circle </em>
<em> p = 2πr + d</em>
<em> perimeter of the semicircle</em>
<em> </em>
<em></em>
<em> P = πr + 2 r (∵ d = 2 r)</em>
<u><em>Step(iii):-</em></u>
<em> From diagram the diameter of semicircle is equal to the width of the rectangle </em>
<em> d = 8</em>
<em> d = 2 r = 8</em>
<em> The radius of the circle 'r' = 4 </em>
<em> perimeter of the semicircle</em>
<em> P = πr + 2 r </em>
<em> P = 3.14 ( 4) + 8</em>
<em> P= 20.56</em>
<u><em>Conclusion:-</em></u>
<em>The perimeter of given figure</em>
<em> = perimeter of rectangle + perimeter of semicircle</em>
= 36 + 20.56
=56.56 ft
Answer:
Step-by-step explanation:
Volume of a pyramid = (l×b×h)/3
V = 128cm^3,
l = 8cm
b = 8cm (/because is a square base)
Substituting this values
128 = (8×8×h)/3
Cross multiply
128×3 = 64h
384 = 64h
Dividing through by 64
h = 384/64
h = 6cm
Height is 6cm
To get the product of (3a + 2) and (4a² - 2a + 9), we can apply the rules of distribution over multiplication and have
3a(4a² - 2a + 9) + 2(4a² - 2a + 9)
12a³ - 6a² + 27a + 8a² - 4a + 18
Adding like terms of the same degree, we can simplify it into
12a³ + 2a² + 23a + 18
Therefore, the answer is D<span>.

Answer:
Step-by-step explanation:
Rate = (20½ pounds)/(4 hours) = (5⅛ pounds)/hour
9 hours × (5⅛ pounds)/hour = 46⅛ pounds
