X³=64/27
Cube root the answer
³√x³=³√64/27
x=4/3.
Check:
x=4/3
x³=(4/3)³
x³=64/27. As a result, the correct answer is 4/3 or 4 over 3. If you wonder why don't I choose the answer as ±4 over 3 because of this
±4/3
Choose positive first
(4/3)²=64/27 Correct. However, then choose negative signs
(-4/3)³=-64/27 Incorrect. Hope it help!

Which is greater, the area of a red plate that has a radius of 6 cm, or the area of two yellow plates with a radius of 3 cm each
sineoko [7]

Answer:

The area of a red plate with radius 6cm is greater.

Step-by-step explanation:

The general formula for the area of a circle is:

A = πr², where 'r' represents the radius

To compare the areas of the plates, we can set up two different equations:

Red plate:  A = π6² or 36π

Yellow plate: A = π3² or 9π

But, there are two yellow plates:

9π + 9π = 18π

36π > 18π, so the area of the red plate is greater.

A 10 ft by 10 ft square garden contains a large walking path through the diagonal what is the area of the walking path shown in
Sindrei [870]

Answer:

64 ft^2

Step-by-step explanation:

Area of shaded part = area of a square = 2 x area of a triangle

area of a square = length^2

10^2 = 100 ft^2

Area of a triangle = (1/2) x base x height

1/2 x 6 x 6 = 18 ft^2

area of shaded part = 100 - 2x 18 = 64 ft^2
