She forgot the 0 in the middle, which is why she got 192. The correct answer is 1812
Step-by-step explanation:
perimeter = 2*length + 2*width
area = length*width
perimeter = 64
Rectangular means all the corners have to be right angles.
If we say it can be a square, then...
perimeter = 4*side
64 / 4 = side
side = 16 meters
So the dimensions would be 16 m x 16 m
Answer:
x = 5, x = -7
Step-by-step explanation:
If you mean find the roots, then x = 5 and x = -7
Because roots makes the equation equal to 0 and 5 - 5 = 0 and -7 + 7 = 0
Answer:
the second one
Step-by-step explanation:
The wrong statement: The volume or the smaller cone cannot be determined because its height is unknown.
We already know that the larger cone has a height of 8 cm and that the smaller cone is just 1/4 of 8 cm.
8×1/4 = 2 cm.
You can still find its volume by using the formula 1/3πr^2.
