Answer:
Just as the square root is a number that, when squared, gives the radicand, the cube root is a number that, when cubed, gives the radicand. Cubing a number is the same as taking it to the third power: 23 is 2 cubed, so the cube root of 23 is 2.

Answer:
Well, with the info I have been given I would say; The L.A of a cylinder is SA+=2(pi)(r)(h).
Step-by-step explanation:
SA=Surface Area
LA=Lateral Area
Pi=3.14
R=Radius
H=Height
V=Volume
LA=2*pi*r*h <-- finds the Lateral Area of a cylinder
SA=LA+2*base or SA=2*pi*r*h+2*pi*r^2<-- finds the Surface Area of a cylinder
V=pi*r^2*h<---- Finds volume of the cylinder
Answer:
The percentage change is 140%
Step-by-step explanation:
Given
---- initial dimension
--- new width
--- new dimension
Required
The percentage increment
The length remains constant because only the width is extended.
The new area is:
Make L the subject
Substitute values for A and W
--- this is the length of the garden
Calculate the initial width:
Make W1 the subject
So, the initial area is:
The percentage change in area is:
Express as percentage
