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.
The volume of a cone is 37x3 cubic units and its height is x units. which expression represents the radius of the cone's base, in units? 1 s o 3x o 6x obx 93x2
The figures below are made out of circles, semicircles, quarter circles, and a square. find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations).
