Can someone help me with 10 math questions (: A cone has a radius of 5 inches and a height of 18 inches.

What is the exact volume of the cone?

A.
150π in3

B.
300π in3

C.
450π in3

D.
540π in3

Answers

Answer 1

Answer: so volue of a cone=1/3 times (area of base[which is a circle]) times height

area of base=area of circle=pi time radius^2
area=pi times 5^2
area=pi times 25=25pi

1/3 times 25pi times 18
25pi times 18 times 1/3
25pi times 18/3
25pi times 6=150pi

the answer is 150π in^3 or 150π cubic inches or C

( to solve, aprox pi to 3.141592 an multiply 150 by 3.141592=471.239 in^3)

Marguerite is building a box from strips of wood. She needs 78 pieces of wood that are each 29 centimeters long. The wood comes in boards that are 6meters long. How many boards will she need?

Answers

First what you need to do is make 6meters into centimetres so what how many meters in a centimetre
100cm so you do 100 x 6= 600
After that you do 600 divided by 28 then by 78 then you will find the answer.

Alice and Amy decide to meet at a party. From a corner of the party hall, Amy spots Alice at the corner of the hall diagonally opposite her. If the party hall is a rectangle that measures 100 feet by 60 feet, what is the shortest distance Amy has to walk to reach Alice? Round your answer to the nearest foot

Answers

Answer:

Distance between Alice and Amy is 117 feet.

Step-by-step explanation:

As shown in the figure attached, Amy spots Alice at the corner of the party hall diagonally opposite her.

If the party hall is in a rectangle shape. Measure of the hall sides are 100 feet by 60 feet.

We know shortest distance from one corner to the other corner is a diagonal.

Therefore, shortest distance between Amy and Alice will be = length of the diagonal = $\sqrt{100^(2)+60^(2)}$

= $√(10000+3600)$

= $√(13600)$

= 116.62

≈ 117 feet

Therefore, Alice and Amy are 117 feet apart.

I think the answer is 100. Let me know if I am wrong.

What is equivelent to
4d+6+2d

Answers

The value of the equation 4d + 6 + 2d is A = 6 + 6d

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

A = 4d + 6 + 2d be equation (1)

On simplifying the equation , we get

A = 4d + 2d + 6

A = 6d + 6

A = 6 ( d + 1 )

Therefore , the value of A is 6d + 6

Hence , the value of the equation is A = 6d + 6

We can add like terms. Like terms are when the variables are alike, so you can add them to get a simpler form of your expression.equation.
4d and 2d are like terms, therefore, we can add them.

6d+6 is what we are left with.

Our final answer: 6d+6 is equivalent to 4d+6+2d

What is the correct answer to 7^2

Answers

Answer:

Step By Step Explanation:

1. Take the number 7.

2. Multiply it by itself: $7 \times 7$.

3. The result is 49.

The "^" symbol is an exponent, which tells you how many times to multiply the base number (in this case, 7) by itself. Since the exponent is 2, you multiply 7 by itself once to get 49.

Answer: 49

Exponentiation is equal to repeative multiplication. If exponent is 2, you multiply number in the basis.

So for
