b) Find the area of the base
c)Divide by 3 at the end
d) Multiply Length time Width
e) Find the height of the cone
Answer:
find the radius of the base
find the area of the base
find the height of the cone
divide by three at the end
Step-by-step explanation:
this is from the formulae of volume of the cone
1/3πr2h
Answer:
c = 30°
d = 60°
Step-by-step explanation:
Angle ZWC is a 90° angle
Angle YWX is a 60° angle
add them together and you get 150°
180 - 150 = c = 30°
c + d + 90° = 180°
substitute
30° + d + 90° = 180°
combine like terms
120° + d = 180°
subtract 120° from both sides
d = 60°
hope this helps!!
Answer:
c is 30 and d is 60

Answer:
Length of an isosceles triangle is, 3.12 m
Step-by-step explanation:
Given: Perimeter of an isosceles triangle is 15.6 m.
Let a be the length of sides and b be the base of an isosceles triangle respectively.
To find the length of the sides(a);
Isosceles triangle is a triangle with two equal sides and two equal base angles.
Perimeter of the isosceles triangle is the sum of the three sides i,e
Perimeter(P) = a +b +a = 2a +b
also it is given that; the base is 3 m bigger than a leg.
⇒ b = 3 a
Substitute this in perimeter formula;
P = 2a +3a =5a
Substitute the value of perimeter = 15.6 m
we have;
Divide both sides by 5 we get;
Simplify;
a = 3.12 m
Therefore, the length of the sides of an isosceles triangle is, 3.12 m
Answer:
The legs are 4.2m long.
The base is 7.2m long.
Step-by-step explanation:
x=leg
y=base
We can write two equations with the information given.
y=x+3
2x+y=15.6
We can solve this as a system of equations.
y=x+3
-(2x+y=15.6) - make the bottom equation negative.
-2x=x-12.6 - add the bottom to the top, canceling out the y.
-2x+12.6=x - add 12.6 to both sides.
12.6=3x - add 2x to both sides.
4.2=x - divide both sides by 3.
x=4.2
Now we can solve for y.
y=x+3
y=(4.2)+3 - substitute in the x.
y=7.2
