A rectangular pool has a length of 60 feet and a width of the square root of 18 feet.
Vsevolod [243]

a).  Area = (length) (width)

               = (60 ft) (√18 ft)

               =     (60 √18)  ft²

               =     60 √(9 · 2)   ft²

               =     60 (3) √2      ft²
 
               =   180 √2           ft²     (about  254.6 ft²)


b).  Volume  =  (length) (width) (height)

                    =  (60 ft) (√18   ft) (√10   ft)

                    =        60 √(180)         ft³

                    =        60  √(4 · 9 · 5)          ft³

                    =        60 (2) (3) √5             ft³    

                    =       360 √5         ft³        (about  805 ft³)

vagabundo [1.1K]

length =88cm

breadth=21cm

when it is rolled it becomes cylinder

having circumference 88cm

2πr=88cm

r=88×7/44

r=14

h=21

total surface area of the cylinder =2πr(r+h).

=2×22/7×14(14+21)

=3080cm²

Find the midpoint of the segment between the points (17,−11) and (−14,−16)
Viefleur [7K]

Answer:

(1.5, -13.5)

Step-by-step explanation:

Midpoint Formula: (\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2} )

Simply plug in our coordinates into the formula:

x = (17 - 14)/2

x = 3/2

y = (-11 - 16)/2

y = -27/2
