The answer is

round cake - 82.42 in²

rectangular cake - 114 in²

Round cake:

d = 7 in

r = d/2 = 7 in / 2 = 3.5 in

h = 2 in

The surface are of a cylinder is:

A = 2πr² + 2πrh

The surface are of the round cake (which is actually a cylindrical cake) excluding the bottom is:

A = 2πr² + 2πrh - πr²

A = πr² + 2πrh

A = 3.14 * 3.5² + 2 * 3.14 * 3.5 * 2

= 38.46 + 43.96

= 82.42 in²

Rectangular cake:

w = 6 in

l = 9 in

h = 2 in

The surface are of a rectangle is:

A = 2wl + 2wh + 2lh

The surface are of the rectangular cake excluding the bottom is:

A = 2wl + 2wh + 2lh - wl

A = wl + 2wh + 2lh

A = 6 * 9 + 2 * 6 * 2 + 2 * 9 * 2

= 54 + 24 + 36

= 114 in²

Step-by-step explanation: This answer is not mine but JcAlmighty’s so all credits go to them.

Step-by-step explanation:

We are given the following in the question:

Hypothesis:

Taking a vitamin supplement each day has significant health benefits and does not have any harmful side effects.

Null hypothesis:

Taking a vitamin supplement each day does not have have significant health benefits.

Alternate hypothesis:

Taking a vitamin supplement each day have have significant health benefits.

Type I error:

  • It the error of rejecting the a true null hypothesis.

A baseball manager is determining the batting order for the team. The team has 9 players, but the manager definitely wants the p
Rina8888 [55]

40320 batting orders are possible.

Since the pitcher bats last, there is only one choice for the 9th slot. For the 1st slot, there are 8 choices remaining. For the 2nd slot, there are 7 choices remaining, etc.

So the number of possible batting orders is:

8*7*6*5*4*3*2*1 = 8! = 40,320

factorial, in mathematics, the product of all positive integers less than or equal to a given positive integer and denoted by that integer and an exclamation point. Thus, factorial seven is written 7!, meaning 1 × 2 × 3 × 4 × 5 × 6 × 7. Factorial zero is defined as equal to 1.

Factorials are commonly encountered in the evaluation of permutations and combinations and in the coefficients of terms of binomial expansions .

Free_Kalibri [48]
First: Find out how many of Jolie's balls are blue.

300 * 35% = 300 * 0.35 = 105 blue balls.

Second: Find the difference between the total number of balls and the blue balls to find out how many green balls Jolie has.

300 - 105 = 195 green balls.
