Which statements are true regarding the area of circles and sectors? check all that apply. the area of a circle depends on the length of the radius. the area of a sector depends on the ratio of the central angle to the entire circle. the area of a sector depends on pi. the area of the entire circle can be used to find the area of a sector. the area of a sector can be used to find the area of a circle.

I’m not sure about that

1.   an exact solution requires a radical solution - no decimal approximation.2. (a)4x^3 = 756x^3 = 756/4 = 189x =   cube root of 189 =   5.74   to nearest hundredth answer(b)   189 = 3*3*3*7   so we can write the cube root of 189 as 3∛7 answerchecking (a) 4*(5.74^3 =   756.48   which is very close(b)   4* ((3∛3)^3   = 4*189   = 756   - spot on! 3. i would use solution b because the original question asked for an exact solution.
