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
Y+4=-3(x-2)
y+4=-3x+6
y=-3x+2 and slope is -3
Answer:
₦28.5
Step-by-step explanation:
Answer:
x=50
Step-by-step explanation:
65/x =13/10
13x=650
x=650/13
x=50
Width be X, length is X+15
area of garden = x(x+15)
area of sidewalk = x(x+15) - (x-4)(x+11) = 632
X^2 + 15X - X^2 - 7X + 44 = 632
8X = 632-44 =588
X= 73.5 >> WIDTH and LENGTH = 88.5
