Answer:
ans: (0,0)
Step-by-step explanation:
to have x- intercepts y = 0
so ,
value of x = -4 and 4 makes y=0
Gradient of a line times the gradient of a line that is perpendicular to it is-1
M1M2=-1
2/3 times M2=-1
M2=-1 times 3/2
The gradient is =-3/2
I’m pretty sure it’s -1
How you solve this is y2-y1/x2-x1
So 5-2/-3-1 which would be -1
8.8 squared + 9.5 squared = square root 12.94 rounded 12.1
The answer is 12π.
To get the volume of the cone, we need the height. The radius is given.
V = πr² × (h/3)
The total surface area of the cone is:
SA = πr² + πrl where r is radius and l is slant height
24π = π(3)² + π(3)(l)
24π = 9π + 3πl
24π - 9π = 3πl
15π = 3πl
l = 15π / 3π
l = 5
Using Phytagoras, we can calculate the height of the cone:
l² = h² + r²
5² = h² + 3²
25 - 9 = h²
h = √16
h = 4
Therefore the volume is:
V = π(3)² × (4 / 3)
V = 3π × 4
V = 12π
