-x^2
Is that x times -x?
positive times a negative is negative
and you add the exponents when multiplying like base
You move the decimal of 1.24 twice and also move the decimal of 11.25 twice because you have to do the same thing two both numbers.
Then now, youre dividing 1125 by 124 and that would equal 9.075
The surface area ratio of the enlarged cube to the original cube is
16:1, or as a fraction, 16/1.If the scale factor is 4,
the edge length of the enlarged cube is 24 cm.(6 × 4 = 24)
To find the surface area of a cube, you can use the formula

, where a is equal to the edge length of the cube.
First, I will solve for the surface area of the original cube.
SA = 6 × 6²
SA = 6 × 36
SA = 216
Next, I will solve for the surface area of the enlarged cube.
SA = 6 × 24²
SA = 6 × 576
SA = 3456
To find the ratio, we divide the original cube's surface area from the enlarged cube's surface area.
3456 ÷ 216 = 16
The surface area ratio of the enlarged cube to the original cube is 16:1, or as a fraction, 16/1.
Answer:
18 centimeters
Step-by-step explanation:
Divide the circumference by π, or 3.14 for an estimation. The result is the circle's diameter.
Divide the diameter by 2.
There you go, you found the circle's radius
