1/10 as a decimal would be 0.1 :)
Answer:
units cubed
Step-by-step explanation:
Let's look at a point (x,y) on the line y=3+x. The height between (x,y) and the x-axis is y. We want the distance from the axis of rotation which is y=3 so the height (or distance between) point (x,y) on y=3+x and y=3 is y-3.
y-3 is the radius in terms of y.
(3+x)-3=x is the radius in terms of x. I replaced y with 3+x since we have y=3+x.
The area of the circle I drew is
To find the volume we must integrate the area of the circle we found between the bounded lines x=0 and x=2.
units cubed
We know the area is length * width.
So we know the length is 8 feet.
The width is 7 + x feet.
Multiply them:
8 * 7 + x.
56 + x.
So option D)
sorry, I misread the options! I meant D) not A)
Answer:
A) Tan 60° = 1.732
B) H = 12 unit
C) Area of triangle = 41.569 unit²
Step-by-step explanation:
As shown in figure, the triangle with cone angle of 60° and base value 4 unit
A) Now, Tan 60° =
Or, Tan 60° = 1.732
B) To find value of h
since TanФ =
So, Tan 60° =
=
∴() × ( = h
∴ h = 12 unit
C) Area of this triangle = × Perpendicular × Base
= × h ×
∵ Perpendicular h = 12 unit
So, Area = × 12 ×
Hence Area of triangle = 41.569 unit²
