Rounded to the nearest hundred cubic meters, what is the total capacity (cone and cylinder) of the storage container?

hichkok12 [17]

The picture in the attached figure

we know that
the total capacity of the storage container=volume of a cone+volume of cylinder

step 1
find the volume of a cone
volume of a cone=(1/3)*pi*r²*h
r=6 m
h=8 m
so
volume=(1/3)*pi*6²*8-----> 301.44 m³

step 2
find the volume of the cylinder
volume of a cylinder=pi*r²*h
r=6 m
h=10 m
s6
volume=pi*6²*10----> 1130.40 m³

total volume=301.44+1130.4-----> 1431.84 m³-------> 1400 m³

the answer is
1400 m³

Suppose a quiz has 12 multiple choice questions. Each question has 4 answer choices. If a student takes the quiz and randomly gu

Gnoma [55]

The probability that the student gets between 1 and 6, exclusive, questions correct will be 0.7872...

Explanation

If the probability of success is $p$ , then the probability of $r$ successes in $n$ trials will be......

$P = ^nC_{r}*(p)^r (1-p)^n^-^r$

Here, the quiz has total 12 questions and each question has 4 answer choices. So, $n=12$ and $p=\frac{1}{4}= 0.25$

The student gets between 1 and 6, exclusive, questions correct. It means there can be 2 or 3 or 4 or 5 questions as correct. So....

The probability of 2 or 3 or 4 or 5 questions correct will be:

$=^1^2C_{2}*(0.25)^2(1-0.25)^1^0 + ^1^2C_{3}*(0.25)^3(1-0.25)^9 +^1^2C_{4}*(0.25)^4(1-0.25)^8+^1^2C_{5}*(0.25)^5(1-0.25)^7\\ \\ =0.2322...+0.2581...+0.1935...+0.1032... \\ \\ =0.7872...$

A)A cylinder with height 4 inches and radius 4 inches.

Step-by-step explanation:

Volume of a Cylinder = \pi r^2 h

Next, we determine the volume of the options being considered by Tommy.

Option A:

A cylinder with height 4 inches and radius 4 inches.

Volume =\pi *4^2*4=64\pi cubic inches

Option B

A cylinder with height 7 inches and diameter 4 inches.

Volume =\pi *2^2*7=28\pi cubic inches

Option C

A cylinder with height 5.5 inches and radius 3 inches.

Volume =\pi *3^2*5.5=49.5\pi cubic inches

Option D

A cylinder with height 6.5 inches and Base Area B = 4 pi inches squared.

Volume =4*6.5*\pi=26 \pi cubic inches

The cylinders in Option A will hold more soup than the other two cans Tommy is considering.

Abdul baked 300 cookies ,480 muffins and 240 cupcakes.Each container should be similar in terms of the numberof cookies, muffins

Reptile [31]

Answer:

(a) 60 cups

(b) 5 cookies, 8 muffins and 4 cupcakes in each container

Step-by-step explanation:

Given

Let:

$C \to Cookies; M \to Muffins; K \to Cupcakes$

So:

$C : M : K = 300 : 480 : 240$

Solving (a): The greatest number of containers to be used;

To do this, we first reduce the ratio to the lowest

C : M : K = 300 : 480 : 240

Divide by 60

$C : M : K = 5 : 8 : 4$

The ratio cannot be further reduced. Hence, he will use 60 cups

Solving (b): The number in each cup

In (a), we have:

$C : M : K = 5 : 8 : 4$

This means that;

$C = 5$ --- Cookies

$M = 8$ --- Muffins

$K = 4$ -- - Cupcakes
