The diagram below gives the dimensions of a swimming pool. 18 ft , 20ft, 36ft (c) What is the total area of the swimming pool? E

WARRIOR [948]

The picture in the attached figure

Part 1) <span>What is the total area of the swimming pool?
</span>
we know that
<span>area of the swimming pool=area rectangle-area semi circle

area rectangle=20*36-----> 720 ft</span>²

area semicircle=pi*r²/2
r=18/2----> 9 ft
area semicircle=pi*9²/2----> 127.17 ft²

area of the swimming pool=720 ft²-127.17 ft²----> 592.83 ft²

the answer Part 1) is
The area of the swimming pool is 592.83 ft²

Part 2) <span>What is the perimeter of the swimming pool?
</span>
perimeter of the swimming pool=perimeter of rectangle-18 ft+perimeter semi circle
perimeter of rectangle=2*[20+36]---> 112 ft

perimeter semi circle=2*pi*r/2----> pi*r
r=9 ft
perimeter semi circle=pi*9----> 28.26 ft
so
perimeter of the swimming pool=112 ft-18 ft+28.26 ft----> 122.26 ft

the answer Part 2) is
122.26 ft

How do the lateral and total surface area of a cylinder differ ?

vichka [17]

The lateral surface area of a cylinder is just the long side connecting the bases, whereas the total surface area includes both the lateral surface area and area of the two circular bases.

$SA_l_a_t=2 \pi rh$ (Imagine a rectangle with the circumfrence of the base as one side and the height as the other being folded around)

$SA = 2 \pi rh + 2 \pi r^2$ (Plus the area of two circles)

The literal difference between surface areas would be the two bases 2πr² if you need that.

How to find missing terms in a arithmetic sequence if there is no middle term?

kozerog [31]

You would use the formula for the specific term you wish to find;
The formula is:
$U_{n} = a + (n - 1)d$
a = starting value of the sequence
d = the common difference (i.e. the difference between any two consecutive terms of the sequence)
n = the value corresponding to the position of the desired term in the sequence (i.e. 1 is the first term, 2 is the second, etc.)
Un = the actual vaue of the the term

For example, if we have the arithmetic sequence:
2, 6, 10, 14, ...
And let's say we want to find the 62nd term;
Then:
a = 2
d = 4
(i.e. 6 - 2 = 4, 10 - 6 = 4, 14 - 10 = 4;
You should always get the same number no matter which two terms you find the difference between so long as they are both consecutive [next to each other], otherwise you are not dealing with an arithmetic sequence)
n = 62

And so:
$U_{62} = (2) + (62 - 1)(4) \\
= 2 + 61(4) \\
= 2 + 244 \\
= 246$

The daily supply of oxygen for a particular multicellular organism is provided by 625 square feet of lawn. A total of 8750 squar

kifflom [539]

Answer:

multicellular organisms = 14

Step-by-step explanation:

given data

multicellular organism = 625 sq feet

total = 8750 sq feet

solution

we will gethere

as we know that 1 multicellular organism = 625 sq feet

we get here multicellular organisms that is

multicellular organisms = ( 8750 ×1 ) ÷ 625

multicellular organisms = 14
