Answer:
96π
Step-by-step explanation:
You will need the formula for the volume of a cone.
π
h
r= 6 cm
To find the height, you need to use the Pythagorean theorem.
a²+ b² = c² (a and b are the 2 legs and c is the hypotenuse)
b = 
b= 
= 8
h= 8 cm
remember PEMDAS!
π
8
π(36)8
π(12)8
V= 96π
Answering in terms of π is more accurate because it is actually infinite so when it gets rounded to 3.14, that is only an approximation of pi. (π is actually 3.1415926535897932384626433 etc.)
Answer:
Length= 30 in
Width= 10 in
Step-by-step explanation:
Let the width of the rectangle be x in.
Length of rectangle
= 3 (width)
= 3x
Perimeter of rectangle= 2(length) +2(width)
80= 2(3x) +2(x)
80= 6x +2x
8x= 80 <em>(</em><em>simplify</em><em>)</em>
x= 80 ÷8 <em>(</em><em>÷</em><em>8</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>
x= 10
Thus width of rectangle= 10 in
Length of rectangle
= 3(10)
= 30 in
If Eli spends $392 for 8 gigabytes of memory, then
, where g is a gigabyte of memory. All you have to do is to reduce the equation. In this case, divide both sides by 8 to get
. So the cost of 1 gigabyte of memory is $49.
Answer:
$40
Step-by-step explanation:
6 = .15x
6 / .15 = 40
