Smallest angle is 30° second largest is 60° largest is 90°
The cost to make this steel cone is $2,543.40.
Step-by-step explanation:
Step 1:
The volume of a cone is determined by multiplying with π, the square of the radius (r²) and height (h). Here we substitute π as 3.14.
The radius of the cone is 9 cm and the height is 10 cm.
The volume of the cone,
So the volume of the cone is 847.8 cubic cm.
Step 2:
If 1 cubic cm costs $3.00, the cost of the given cone is the volume multiplied by the unit cost.
The cost to make the steel cone
The cost to make this steel cone is $2,543.40.
Answer:
-4,-4
Step-by-step explanation:
let the numbers be x and y.
x+y=-8
y=-x-8
xy=16
x(-x-8)=16
-x²-8x=16
x²+8x+16=0
x²+4x+4x+16=0
x(x+4)+4(x+4)=0
(x+4)(x+4)=0
x=-4,-4
-9x-6a+3+6x+a
combine like terms
1. (-9x+6x)+(-6a+a)+3
2. -3x-5a+3
thats is ur answer
hope this helps!
