A cylindrical cake with a height of 5 inches has a 30 degree slice removed. If the volume of the removed slice is 40 inches what is the approximate radius of the cake

Step-by-step explanation:

Given

Height of cylindrical cake is

slice is removed

Volume of the slice is

Area of slice is

Volume of slice will be multiplication of area and height

Hence, the radius of the cake is

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
