<h2>Answer:</h2>
a. is the correct option
<h2>Step-by-step explanation:</h2>The graph of a function and its inverse function
are related to each other. The relationship between these two graphs can be explained by taking a point
that is on the graph of
, then point
must lie on the graph
and vice versa meaning that the graph of
is a reflection of
in the line
. The only graph that meet this requirement is the option a. For instance, the point
is on the graph of
while the point
is on the graph of
as indicated below.
The volume of cone is 75.4 cubic centimeters and the volume of cylinder is 197.92 cubic centimeters. The volume of composite figure is 273.32 cubic centimeters.
Step-by-step explanation:
The given is,
Composite figure made of a cone and a cylinder.
A cone has a height of 8 centimeters and radius of 3 centimeters.
A cylinder has a height of 7 centimeters and radius of 3 centimeters.
Step:1
Volume of composite figure = Volume of Cone +
Volume of cylinder............(1)
Step:2
Formula for volume of cone,
....................(2)
Where, r - Radius of cone
h - Height of cone
From the given,
r = 3 centimeters
h = 8 centimeters
Equation (2) becomes,
= (3.14 × 9 × 2.667) (∵ = 3.1415)
= 75.4
= 75.4 cubic centimeters
Step:3
Formula for volume of cylinder,
....................(2)
Where, r - Radius of cylinder
h - Height of cylinder
From the given,
r = 3 centimeters
h = 7 centimeters
Equation (2) becomes,
= (3.14 × 9 × 7) (∵ = 3.1415)
= 197.92
= 197.92 cubic centimeters
Step:4
Equation (1) becomes,
Volume of composite figure = 75.4 + 197.92
= 273.32 cubic centimeters
Result:
The volume of cone is 75.4 cubic centimeters and the volume of cylinder is 197.92 cubic centimeters. The volume of composite figure is 273.32 cubic centimeters.
