The formula for the volume of a cone is V=(1/3)πr^2h.
To find r (radius) divide the diameter by 2, giving you 2.5 cm.
Plug in the numbers now !
V=(1/3)(3.14)(2.5^2)(9)
V=(1/3)(3.14)(6.25)(9)
V=(1/3)(176.625)
V=58.875
Therefore, the volume of the cone is about 59cm^3 :)
The area of the triangle is 30 units^2. the height of the triangle is 4 units.
<h3>What is the area of the triangle?</h3>
The area of the triangle is defined as the product of half the base and the height of the triangle.
The area of the triangle can be calulated by the herons formula
base of ABC = AC = 15 units
Height of ABC = 4 units
Semi perimeter s = 5 + 12.65 + 15/ 2 = 32.65 / 2 = 16.32
Herons formula

Area of ABC is 30 units^2 approximately.
Height of the triangle = 2( area) / base
= 2( 30) / 15
= 4.
WE can see that
Area of ABC = 1/2 (base) (height)
= 1/2 (15 units) (4 units)
= 30 units^2

Answer:
39°
Step-by-step explanation:
For a straight line, the sum of angle is 180°
At the point where we have the 107°, the inner angle in the triangle will be 180-107=73°
68° is alternate angle to the inner angle in the triangle
Since the sum of angles in a triangle are 180°, then angle x will be
X=180-73-68=39°
Therefore, missing angle is 39°
