we know that
2pi radians (full circle) has an area of-----------------> 100pi
then
(2pi/5) radians----------------------------> X
X=(2pi/5)*100pi/2pi---------> 20pi units²
the answer is
20pi units²
Answer:
1256 cubic yards of sand.
Step-by-step explanation:
In this question we have to find the volume of cone formed by sand.
Height of the cone is = 36 feet
Radius of the cone = 60/2 =30 feet.
Now we know the formula of volume of cone v = π r² (h/3)
By putting the values of r and h we can get the volume of sand to spread.
Volume = π×(30)²×(36/3) = 3.14×900×12 feet³
= 33912 feet³
Now we will convert feet³ to cubic yards
Since 1 cubic feet = .037037 cubic yards
therefore 33912 cubic feet = 33912×.037 = 1256 cubic yards.
So the answer is 1256 cubic yards of sand has the department received.
Candice drove 22 miles. 66 divided by 3 is 22. Which means Marcos drove 44 miles.
Answer:
$5,250
Step-by-step explanation:
2/7x - [4/5(2/7x)] = 300
2/7x - 8/35x = 300
10/35x = 8/35x = 300
2/35x = 300
2x = 10500
x = 5250
