Find the area of the following ellipse. a = 4.5 m; b = 5.5 m
LenaWriter [7]

Answer:

Area of ellipse is ≈ 77.78 m^{2}

Step-by-step explanation:

Given the dimension of ellipse

  a = 4.5 m

  b = 5.5 m

Now, Area of ellipse = \pi ab

                                  = \frac{22}{7}\times 4.5\times 5.5

                                  = \frac{5445}{70}

                                  = 77.78 m^{2}

Hence Area of ellipse will be 77.78 m^{2}

An Olympic-sized swimming pool holds 2,500,000 liters of water. How many gallons of water does an Olympic-sized swimming pool ho
tankabanditka [31]

Answer:

The Olympic sized swimming pool hold 660501.9 gallons of water.

Step-by-step explanation:

Given that:

Water hold by an Olympic sized swimming pool = 2500000 liters

We know that;

1 gallon = 3.785 liters

Therefore,

We will divide the total number of water in liters by 3.785 to find the number of gallons.

Gallons of water in pool = \frac{2500000}{3.785}

Gallons of water in pool = 660501.9 gallons

Hence,

The Olympic sized swimming pool hold 660501.9 gallons of water.
