Answer:
exact area = 81π in.²
approximate area = 254.34 in.²
Step-by-step explanation:
Exact:
area = πr²
r = radius = diameter/2 = 18 in./2 = 9 in.
area = πr²
area = π × (9 in.)²
area = 81π in.²
exact area = 81π in.²
Approximate:
π = 3.14 (approximately)
area = πr²
area = 81π in²
area = 81 × 3.14 in.²
approximate area = 254.34 in.²
6/8 would be simplified by to so, 6/8 = 3/4
Hope this helps u out :D
Answer:
The GCF is 3w
Step-by-step explanation:
You have to find the GCF of
6w^3, 3w^2, 9w
You can start with 3. Then get:
6w^3/3 = 2w^3
3w^2/3 = w^2
9w/3 = 3w
The following factor is w. It has to have an exponent of one, as it the smallest exponent present in the 3 numbers:
2w^3/w = 2w
w^2/w = w
3w/w = 3
Expression:
6w^3 - 3w^2 - 9w= 3w(2w^2 - w - 3)
The GCF is 3w.
Answer:
10%
Step-by-step explanation:
1/10 = 10/100 = 10% (by definition of what percentage is)
Answer:
Step-by-step explanation:
Red = 6
Blue = 3
Green = 5
Total = 14
First marble = 6/14 = 3/7 You now have 5 reds and 13 total
Second Marble = 5 * 13 which brings you down to 4 red and 12 total.
Third Marble = 4/12 = 1/3
Result
P(3 Red) = 3/7 * 5/13 * 1/3 cancel the 3s
P(3 Red) = 1/7 * 5/13
P(3 Red) = 5/91
P(3 Red) = 0.0549 . Rounding to the nearest 1/100 depends on what you have been told about rounding. I would say the answer is 0.05 but your teacher may say something different.
