<u><em>Answer:</em></u>
volume of sphere = 288π ft³
<u><em>Explanation:</em></u>
volume of sphere = 
where pi is a constant and r is the radius of the sphere
<u>We are given that: </u>
The diameter of the sphere is 12 ft.
<u>This means that</u> the radius = 
<u>Substitute with the radius in the above equation to get the volume as follows:</u>
volume = 
ft³
Hope this helps :)

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) isThe area of the swimming pool is 592.83 ft²Part 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) is122.26 ft
Yes, I do like your pfp it looks very cool
Answer:
u probably need to just count the boxes. some are half so take it as 0.5
let the size of each box be 1 cm.
1) 14 cm or 14 unit (i m sure for this one)
2) it would approximately be 15 unit
my teacher taught me if the boxes are have different measurement other than half so just don't count that
u will fine your answers at the back of your textbook
