Answer:
Step-by-step explanation:
Given:
radius of cone = 3 inch
Total area of cone = 
Find the volume of the cone?
We know the area of cone = 
-------(1)
Where r = radius
Ans s = side of the cone
Put the area value in equation 1
-------(1)
Put r value in above equation.
The side s = 5 inches
We know the side of the cone formula
Put r and s value in above equation.
The volume of cone is
Put r and h value in above equation.
The Volume of the cone is
Answer:
56
Step-by-step explanation:
The angle sum theorem *I think* is that for an n-sided shape, the total sum of its angles is 180(n-2).
The sum of a triangles' angles is 180 degrees.
Therefore 4v-44 = 180.
v - 11 = 45
v = 56 degrees
Note: always check if the answer makes sense
3x-4y=12
4y=3x-12
y=(3x-12)/4
y=(3/4)x-3
Answer:
y = 108x + 216
Step-by-step explanation:
given
y = 4x³ then 
= 12x² = 
x = 3 ⇒ m = 12(- 3)² = 108
equation of tangent in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept ), hence
y = 108x + b
To find b substitute (- 3, - 108) into the equation
- 108 = -324 + b ⇒ b = - 108 + 324 = 216
y = 108x + 216 ← equation of tangent
