lisabon 2012 [21]

Answer:

329.91 cm^2

Step-by-step explanation:

A ring-shaped region is shown below. Its inner radius is 8m, and its outer radius is 11m. 8m 11m Find the area of the shaded region. Use 3.14 for π. Do not round your answer.

Your answer

Given data

inner radius= 8cm

area= πr^2

area= 3.142*8^2

area= 3.142*16

area= 50.272 cm^2

outer radius= 11cm

area= πr^2

area= 3.142*11^2

area= 3.142*121

area= 380.182 cm^2

Hence the area of the shaded part is

=380.182-50.272

=329.91 cm^2

4a. Riley is buying things for a holiday party that she is having. She wants to make a cheese and cracker appetizer; every crack
S_A_V [24]

4a.

We can get the least number by taking LCM of 24 and 16.

We list each of the numbers as prime factors and take the mutiplication of each unique prime factor that occurs the greatest number of times.

24 = 2 * 2 * 2 * 3

16 = 2 * 2 * 2 * 2

So,

2 occurs four times

3 occurs 1 times

LCM of 24 and 16 is:

2 * 2 * 2 * 2 * 3 = 48

Least number of cheese and cracker appetizer = 48

4b.

Sleeves are sold in 24.

So, to get 48, she would need to buy:

48/24 = 2 sleeves

4c.

Cheese slices comes in packages of 16. So she needs to buy:

48/16 = 3 packages of cheese
