Shelton drew a circle with a radius ir 10 centimeters. he than shaded 2 portions of his circle. find the area of the shaded portion of shelton's circel

The Area of shaded portion is 314000 cm²

Step-by-step explanation:

Given as :

The circle is drawn with radius = r = 10 cm

Two portion of circle is shaded

∵ two portion is shaded means whole the circle is shaded now

Let The area of shaded portion = A = area of circle

∵ Area of circle = A = π × radius²

where π =  3.14

Or, A = 3.14 × r²

Or, A = 3.14 × (100)²

Or, A = 3.14 × 10000

Or, A =

I.e A = 314000 cm²

So, The Area of shaded portion = A =  314000 cm²

Hence, The Area of shaded portion is 314000 cm²   Answer

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
