The circumference of any circle is (pi) x (the diameter of the circle).
The problem gives you both numbers, so all you have to do is multiply them.
Circumference = (pi) x (diameter) = (3.14) x (21cm) = <em>65.94 cm .</em>
Factor then solve. Exact Form: x = 0 , 7 + √ 97 2 , 7 − √ 97 2 Decimal Form: x = 0 , 8.42442890 … , − 1.42442890 …
Answer:
6xy(15xy−1)
Step-by-step explanation:
Answer:
minimum value of function is 
.
Step-by-step explanation:
Given function represents a parabola.
Now, here coefficient of 
is positive , so the parabola will be facing upwards and thus the function will be having a minimum.
Now, as we know that minimum value of a parabolic function occurs at
x = 
.
Where , b represents the coefficient of x and a represents the coefficient of .
here, a = 2 , b = -6
Thus = 
= 
So, at x = minimum value will occur and which equals
y = 2×
- 
+ 9 = .
Thus , minimum value of function is .
Answer:
180 ft^2
Step-by-step explanation:
larger box: 8*3*5 = 120
here we see that one side of the smaller box is unlabeled. but the total side length is 7, and the larger box is 3 long, so:
smaller box= (7-3)*3*5 = 60
total=120+60=180
