What the circumference of the base?
What the circumference of the base? - 1

Answers

Answer 1
Answer:

The formula for the circumference of a circle is:

C = 2πr

The radius (r) is half of the diameter, so to find the radius just divide the diameter by two...

radius = 20 ÷ 2

radius (r) = 10 m

Plug in what you know into the formula for the circumference:

C = 2π(10)

C = 20π

The exact circumference is: 20π m

The approximate circumference is: 63 m

Hope this helped!

What measurements do you need to know to find the volume of a cylinder? a cone? a sphere

Answers

For the volume of a cylinder, it is volume=base times height.
For the volume of a cone, it is volume=1/3 times base times height.
For the volume of a sphere, it is volume=4/3 times pi times r^{3} 

For a cylinder you need radius and height
Cone you need radius and height
Sphere you need radius.

For a cylinder you need radius and height

cone you need radius and height

sphere you need radius.

Y= 6x + 4 and y= 4x - 2

Answers

easy
sub since boht equal y, both are equal
6x+4=y=4x-2
6x+4=4x-2
minus 4x
2x+4=-2
minus 4
2x=-6
divide 2
x=-3
sub back
y=4x-2
y=4(-3)-2
y=-12-2
y=-14

solution in (x,y) form is
(-3,-14)
matrix or it can be y=4
