Answer:
2.83
Step-by-step explanation:
Pathogrean theorem.
(forgive my spelling)
2^2+2^2=b^2
4+4=b^2
8=b^2
rad8=radb^2
rad8 = b

Answer:
volume of a cone = 461.58cm³
Step-by-step explanation:
to find the volume of a cone
given the radius of the cone = 7cm
height of the cone = 9cm
recall that the volume of a cone = πr² h/3
volume of a cone = 3.14 x 7² x 9/3
volume of a cone = 3.14 x 49 x 3
volume of a cone = 3.14 x 147
volume of a cone = 461.58cm³
therefore the volume of a cone whose radius is 7cm , height is 9cm is evaluated to be equals to 461.58cm³
Let's break down each part of this question into math symbols. It's cooler to think of it like one of those codes they make you crack in primary school.
Three: 3
Times: * (multiplication)
A number: x
Less two: –2
Is greater than: >
Two: 2
No more than: <
Seven: 7
So 3*x–2>2
But also
3*x–2<7
Solving the first equation, add two to both sides:
3x>4
Divide both sides by 3:
X>4/3 (4/3 is about 1.33)
Solving the second equation, add two to both sides:
3x<9
Divide both sides by 3:
x<3
So the number we want is bigger than 1.33 but less than 3 which makes the answer:
2
