How many circles of radius 1 can fit into circle of radius 500?
Gekata [30.6K]

using 3.14 for Pi , since you didn't say what value to use

area = PI x r^2

 Area of larger circle = 3.14 x 500^2 = 785,000 square units

area of smaller circles = 3.14 x 1^2 = 3.14 square units


785,000/ 3.14 = 250,000 small circles can fit into larger one

The surface of a pool table has a perimeter of 26 feet and an area of 36 square feet. What are the dimensions of the pool table?
deff fn [24]

Answer:

Step-by-step explanation:

pool tables are rectanglar

Perimeter = 2L + 2W      =  2(L+W)   ---->>>    Perimeter/2  = L + W  =

         Perimeter/2 - W  =  L

        Area = L×W     

Two equations and two unknowns and  L is substituted into the area equation  

 ---->>  Area = (Perimeter/2 - W) x W

          Area = (Perimeter x W)/2  - W²              solve for W

Area = 36 and  Perimeter = 26

       36 ft² = (26)( W)/2 ft  - W² ft²

       36 ft² = 13W ft - W² ft²

        W² - 13W + 36 = 0            quadratic equation factor solve for W

         (W - 4)(W - 9)  = 0            

There are two roots

        W - 4 = 0   and W - 9 = 0

        W = 4  and  9         W = 9  it doesn't make sense  needs to be < L

Perimeter/2 - W = L

         L = 26/2 - W

            = 13 - 4

         L = 9 ft  and   W = 4 ft
