Answer:
1, 42
Step-by-step explanation:
Another pair of factors of 42 would be 2, 21. Factors, when multiplied, would get 42. 6,7 would also work, etc etc.
Answer:
7.5π
Step-by-step explanation:
First we should get the entire circle's circumference with 2rπ
2 * 5 * π = 10π
Now, because whats missing is a 90° arc, which is 1/4 of the circle, we can say the the rest of it is 3/4 of the circumference.
3/4 * 10π = 7.5π
Answer:
Step-by-step explanation:
point - slope formula: y - y1 = m(x-x1)
we need to find the slope ... or what is m ?
m = rise / run
m = y2 - y1 / x2 - x1
where the given points are (x1,y1) and (x2,y2)
m= 7-5 / 6-5
m = 2 / 1
m =2
now use either point and plug the slope and the point into the point-slope formula
y-5 =2(x-5) :)
Answer:
The radius of the silo is 5.788 feet.
Step-by-step explanation:
Since the silo has the shape of a cylinder, then;
Volume of the silo = Volume of a cylinder = 
h
Where: r is the radius of the silo, and h is the height.
Given that: volume = 2106 cubic feet, and height = 20 feet.
Then,
2106 = 
x x 20
2106 = 
2106 x 7 = 440
14742 = 440
= 
= 33.5045
⇒ r = 
= 5.78831
r = 5.788 feet
The radius of the silo is 5.788 feet.
