The diameter of the face-off circle on an ice-hockey rink is 30 feet. Find its area.

Answers

Answer 1

Answer:

The area is 706.86 ft sq  

Answer 2

Answer:

706.86 sq ft. (or 706.5 sq ft if 3.14 is used as pi)

Step-by-step explanation:

the formula for the area of a circle is πr2^. We know our diameter is 30 ft, and since radius is half of the diameter, that means our radius is 15 ft. Now we plug this into the formula, which would be 3.14x15^2. type this into the calculator to get our area of 706.5 sq ft.

hope this helped!!!

How can x minus two-thirds = StartFraction 5 over 6 EndFraction be solved for x in one step?
Add Two-thirds to both sides.
Add StartFraction 5 over 6 EndFraction to both sides.
Subtract Two-thirds from both sides.
Subtract StartFraction 5 over 6 EndFraction from both sides.

Answers

Add Two-thirds to both sides

solution:

x-2/3= 5/6

We have to find how this can be solved for "x" in one step

Remember that,

We we add or subtract same number from both sides of a equation, the equation still remains true

Therefore, from given,

x-2/3=5/6

Add Two-thirds to both sides

x-2/3+2/3=5/6+2/3

x=5/6+2/3

x=9/6

Add Two-thirds to both sides to solve the sum

Answer:

A.

Add Two-thirds to both sides.

A packaging firm has been hired to create a box for baby blocks. The firm was hired because it could save money by creating a box using the least amount of material. the packaging firm knows that the volume of the box must be 18cm^3.

A. What are the possible dimensions for the box if the volume must be18 cm3?

B . Which set of dimensions should the package firm choose in order to use the least amount of material? Explain Please show work

Answers

Answer:

A. 3cm by 3cm by 2cm or 6cm by 3cm by 1cm

B. 3cm by 3cm by 2cm

Step-by-step explanation:

POSSIBLE DEMENSIONS

3cm by 3cm by 2cm = 18cm^3

6cm by 3cm by 1cm = 18cm^3

LEAST AMOUNT OF MATERIAL

3 by 3 by 2 would mean 6cm squared of material per side

6 + 6 + 6 + 6 + 6 + 6 = 6 times 6 = 36

Total : 6 sides = 36cm^2 used

6 by 3 by 1 would mean 2 sides of 6cm^2, 2 sides of 3cm^2 and 2 sides of 18cm^2

18 + (6 + 6) + (3 + 3) =

18 + 12 + 9 =

30 + 9 = 39

Total: 39cm^2

Adding negative number is just like adding positive numbers. Just add the numbers like normal and put a negative sign in front of it!

Just think of it as 2.8+3.5

Answer:

The answer is A.-49

number 2 is 0.7

Step-by-step explanation:

Scince they are negative, adding is technically making the number lower, so

-16+-33=-49

2. Is 0.7 because if you convert 2 and 8/10 into decimal form it's 2.8

So 2.8 plus -3.5 is 0.7
