Find the area of a circle with a circumference of 31.4 units.

Answers

Answer 1

Answer:

area = 78.46

Step-by-step explanation:

31.4 = 2pi * r

divide 31.4 by 2 and get 15.7

15.7 = pi * r

divide 15.7 by pi and get

4.997 = r

(4.997^2) * pi = 78.46

June, Mitchell and Nick are the ones who drew the line of symmetry correctly because if you were to cut that in half, both sides remain the same shape and size.  Stephanie, Liz, and Brandon are wrong because if you cut that you get different shapes and sizes, they will not be identical.

June did

Answer:

250 gallons of water are being pumped out each hour

Step-by-step explanation:

It tells us that W is the amount of water in the pool at a time. It also tells us that at the start there is 9000 gallons in the pool. We also know t is the time in hours so 1 t = 1 hour.

W=9000-250t

We can substitute in what we know

The amount of water in the pool = 9000 gallons - 250 gallons times 1 hour

so that means if one hour passes 250 gallons are removed, and if 2 pass then 500 are removed showing that for every hour the pump is on 250 gallons of water are being sucked from the pool

From the numbers between 11 and -14
Number of terms: 6
First term: -14
6th term = 11
a + (n-1)d = -14
11 + (6-1)d = -14
11 + 5d = -14
5d = -25, d = -5

From 11 you subtract 5 to the left
d = 6, c = 1, b = -4, a = -9

Which is the smallest non-negative?

Solution: c

Answer: 37/12

Step-by-step explanation: First you must turn 2 1/6 into a improper fraction, so 2x6 + 1 will get you 13 as the numerator and the denominator will be 6 so now we have 13/6 + 11/12. Now we must turn the denominator for 13/6 into 12 so, 13x2/6x2 so it is 26/12 so now the equation is 26/12 + 11/12 is 37/12.

When osteoporosis occurs, the holes and spaces in the honeycomb are much larger than in healthy bone. Osteoporotic bones have lost density or mass and contain abnormal tissue structure. As bones become less dense, they weaken and are more likely to break. Osteoporotic bone breaks are most likely to occur in the hip, spine, or wrist. In addition to causing permanent pain, osteoporosis causes some patients to lose height.
