The formula for area is pi x r^2 (pi times radius squared) so, for number 7 youre given the radius or "r", which is half the length of the inside of the cirlce. On a calculator: you would do 8 times 8 (8^2) because that's the radius squared and then you should get 64 and times 64 by 3.14 or use the pi button depending on what your teacher prefers you to use.
When you're given diameter or "d" which represents the is equal to the radius times 2. So, for example, number 8 the diameter is 26 so, the radius is 13. Use the formula for area just like in number 7 to find the area of this circle.
Make sure you pay attention to what information youre given (whether its "d", Diameter, "r" or radius. Use those two lists of steps for solving numbers 7 through 12.
For numbers 13-15: use the number (22/7) instead of 3.14 or the pi button on your calculator and do the same steps!!!!!
Let me know if you still need help after this:) happy math solving!
Answer:
40
Step-by-step explanation:
you add all the numbers up then divide by how many numbers there are
The rate per hour is equal to the total bagels made divided by the time to make them.
360 ÷ 10 = 36
If for 1 hour they make 36 bagels, for 13 hours they can bake
36 x 13 = 468 bagels.
Answer:
elevation of 3,234 feet above sea level Positive
losing $32.50 Negative
depositing $230 in an account Positive
withdrawing $2,432 from an account Negative
2°C below 0°C Negative
10 floors above ground level Positive
Step-by-step explanation:
elevation of 3,234 feet above sea level Positive This is above ground
losing $32.50 Negative it is less than you had
depositing $230 in an account Positive putting money in
withdrawing $2,432 from an account Negative taking money out
2°C below 0°C less than 0
10 floors above ground level above 0

Answer: VX = 37</h3>
=======================================================
Explanation:
VX is a midsegment and it is half as long compared to the parallel side UY. This means UY is twice as long compared to VX
UY = 2*(VX)
s = 2*(s-37)
s = 2s - 74
s-2s = -74
-s = -74
s = 74
This makes UY be 74 units long
So VX = (1/2)*UY = 0.5*74 = 37
