Answer:
60π
Step-by-step explanation:
Hullo :D
I think this will be a piece of helpful info:
<em>The formula for finding the area of a circle if πd.</em>
<em />
In that case, we just substitute 60 (our d)
So the area will be 60π
If you want that multiplied, you'll get 188.4 (multiplying by 3.14)
Thus, the answer is .
Step-by-step explanation:
7+8+10=25cm is the possibile perimeter of this
triangle.
To find that out, we must find out how much larger <DEF is than <ABC
So we take the sides DE and divide it by AB
4.5/3=1.5
That means <DEF is 1.5 times larger than <ABC
So now, we take BC, and multiply it by 1.5
2 x 1.5 = 3
So EF=3
Hope this helps!
Answer:
Upper Control Limit for a c-chart = 9.1
Step-by-step explanation:
Given - construction company has just constructed 150 new apartments. An external inspector is hired to do the final checking before they are given way to prospective customers. Inspector at random selects 8 apartments and and counts how many defects are in each one them. He finds 7,3, 2, 1, 2, 5, 4, 4 defects.
To find - What will be Upper Control Limit for a C chart ?
Proof -
Upper Control Limit for a c-chart = c bar + 3(square root of c bar)
Now,
c bar = = 3.5
∴ we get
Upper Control Limit for a c-chart = 3.5 + 3(square root of 3.5)
= 3.5 + (1.87)
= 3.5 + 5.61
= 9.1
⇒Upper Control Limit for a c-chart = 9.1
