Answer:
19
Step-by-step explanation:
8 x 4 = 32
32 + 6 = 38
38 / 2 = 19
Answer:
<em>r=3x</em>
Step-by-step explanation:
<u>The Volume of a Cone</u>
The volume of a cone of radius r and height h is:
We are given the volume of a cone is
Equating:
Multiplying by 3:
Simplifying by pi:
Since h=x:
Dividing by x:
Taking square roots:
Thus: r=3x
Answer:
1708.58658058
Step-by-step explanation:
Total surface area formula = (π×r²)+(π×r×s)
r = radius
s = slant height
So we substitute the values into the formula (π×r²)+(π×r×s)
(π×14.2²)+(π×14.2×24.1) = 1708.58658058
Answer:
Step-by-step explanation:
When rotating a point 90 degrees counterclockwise about the origin our point A(x,y) becomes A'(-y,x). In other words, switch x and y and make y negative.
