two clocks are circular. clock a has twice the area as clock b. how many times greater is the radius of clock a than the clock b radius

The radius of clock A is √2 greater than the radius of clock B

The radius of clock A is 1.41 greater than the radius of clock B

Step-by-step explanation:

* Lets talk about the similar circles

- All the circles are similar because all the circles have the same

 measure 360° and there is a ratio between their radii

- If the ratio between the radii of two circles is a/b, then the ratio

 between their circumferences is also a/b

- If the ratio between the radii of two circles is a/b, then the ratio

 between their areas is (a/b)²

* Now lets solve the question

- Clock A has area twice the area as clock B

∴ Area of circle A = 2 Area of circle B

- If the ratio between their radii is a/b

∵ Area of circle A /area of circle B = 2

∴ (a/b)² = 2 ⇒ take a square root for both sides

∴ a/b = √2

∴ The radius of clock A is √2 greater than the radius of clock B

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
