those desert people ought to use less water
The factor that multiplies with 6 to get 18 is 3 but the factor that multiplies with 6 to get 30 is 5.
The numbers in parenthesis should be a 5 and not a 10.
18 + 30 = 6(3 + 5)
Answer:
V = 288.5 
Step-by-step explanation:
To find the volume of a cone, use this equation:
r = radius
h = height
We aren't given the height of the cone, just the length of the side. To find the height use the Pythagorean Theorem:
The value of 12.1 yds is the hypotenuse and the radius is the value of one of the legs. So, set it up like this:
Now, solve:
Distribute the square
Subtract 25 from 146.41
a = 11.01862
So, the height is equal to 11.01862 yds.
Now, we can plug everything into the volume equation:
Simplify (use calculator):
V = 288.5
So, the volume of the cone is equal to 288.5
Answer:
a²+b²=c²
7.5²+9²=c²
137.25=c²
√137.25=c²
11.72.... = c
The Radius of the circle is approximately 11.72cm
Step-by-step explanation:
Using this data. Create a Triangle with the Chord and Center of the dot. We know the distance between the chord and center which is one length of one of the sides.
We split the chord from the intersecting line from the center to the chord making the second line being 7.5cm
After We draw a line from the center of the circle to where the chord meets to the edge of the circle to create the triangle
We now have 2 measurements and can use Pythagorean Theorem to determine the radius from the missing length of the triangle.
