You do 120+48+92=280 All angles in a quadrilateral add up to 360, so 360-280=80 The answer is 80 HAVE FUN DOING MATHS!

Answer:

Measure of fourth angle of quadrilateral is:

100

Step-by-step explanation:

We know that the sum of angles in a quadrilateral is 360°

Three of the angles of a quadrilateral are 120 48 and 92

we have to find the sum of the fourth angle of the quadrilateral

Let measure of fourth angle be x

120+48+92+x= 360

i.e. 260+x = 360

Subtracting both sides by 260, we get

x= 100

Hence, Measure of fourth angle of quadrilateral is:

100

Answer:

Step-by-step explanation:

We know that:

-measuring a cone
-diameter: 18 units
-height: 8 units

We need to know how to find the volume of this cone. To do this, we need the equation to find the volume of a cone:
$V= \pi r^2\frac{h}{3}$ where r=radius and h=height

Upon assessing this equation we also now know that we are missing a radius.

For a circle, the radius is the distance from the midpoint, center, to the border of the circle. The diameter is the distance from the border of one circle to another, passing through the midpoint. Knowing this, we can conclude that the diameter is two times the radius.

Using this information we can figure out the radius for this cone: 9 units.

Now that we have the radius, we can plug in the rest of the numbers with the correct placements.

$V= \pi 9^2\frac{8}{3}$ square the 9 by calculating 9 times 9.
