Answer:
1.) can not be found
2.)V=11403.98
3.)
Step-by-step explanation:
volume = π r×r × H
r = Radius
H = height
π = 3.14
the first one does not have a radius so therefore we can NOT find the volume
the second one is π×(11×11) ×30 =11403.98
the 3rd one is π× (10×10) ×5 =1570.79
hope this helped
Answer:
1
Step-by-step explanation:
Given:
The function is:

To find:
The inverse of the given function, then draw the graphs of function and its inverse.
Solution:
We have,

Step 1: Substitute
.

Step 2: Interchange x and y.

Step 3: Isolate variable y.


Step 4: Substitute
.

Hence, the inverse of the given function is
and the graphs of these functions are shown below.
17. Area of triangle: 1/2bh
1/2 * 12 * 15
1/2 * 180
=90 cm^2
18. Area of trapezoid: 1/2 h (b1 + b2)
1/2 * 8 ( 12 + 15.4)
4 * 27.4
= 109.6 cm^2
