Find the area of the shaded region 40 degrees and raduis 9 cm in a circle use pi 3.14?

Sure thing, darling! To find the area of the shaded region in a circle with a central angle of 40 degrees and a radius of 9 cm, you first calculate the area of the entire circle using the formula A = πr^2. Then, you find the fraction of the circle that the shaded region represents, which is 40/360. Multiply this fraction by the total area of the circle to get the area of the shaded region. Easy peasy lemon squeezy!

How many rectangular prisms can be formed by using exactly 36 cubes?

To determine the number of rectangular prisms that can be formed using exactly 36 cubes, we need to find all the possible combinations of dimensions that can multiply to give 36. The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36. Each factor corresponds to a unique rectangular prism. Therefore, there are 9 different rectangular prisms that can be formed using exactly 36 cubes.

How many number combinations are possible with 0123?

16 if you include 0 starting

12 if not

That is not correct.

0123 is a 4-digit number = (n)

therefore n! = 4! = 1*2*3*4 = 24 (if 0 is included as I assume that is the question)

123 is a 3-digit number = (n)

Therefore n! = 3!= 1*2*3 = 6
