Start with the given formula for the surface area of a sphere.
Now substitute 2x + 5 in for r, the radius.
Then simplify the expression and write it in standard form.
Answer:
(4x+1)= 81
Step-by-step explanation:
4x+1= 81
4x= 81 - 1
4x= 80
x= 80/4
x= 20
Answer:
f average = 1
smaller value c = 3

Step-by-step explanation:
The expression that represents the volume of the composite figure is: 1/3(8)(6)(6) + (8)(6)(4).
<h3>What is the Volume of a Composite Figure?</h3>
The volume for the given composite figure = volume of the rectangular pyramid + volume of rectangular prism.
= 1/3(l)(w)(h) + (l)(w)(h)
Thus, with the given dimensions, plug in the values to get the expression represents the volume of the composite figure:
Volume = 1/3(8)(6)(6) + (8)(6)(4)
