Answer:
The alarm bell will ring at 473 psi.
Step-by-step explanation:
To answer this, find 215% of 220 pounds per square inch:
Convert the percentage 215% to its decimal fraction equivalent, 2.15, and then multiply 220 pounds per square inch by it:
2.15(220 psi) = 473 psi
The alarm bell will ring at 473 psi.
The equation of a line that passes through
and has a slope of m is
so given the point (3,1) and slope -2
(3,1), (x1,y1)
x1=3
y1=1
m=-2
the equation is
Answer:
Radius is 24 centimeters
Diameter is 48 centimeters
Circumference is 150.72 centimeters
Step-by-step explanation:
We have been given that area of the circle B is 1808.64 square centimeters.
We can find the radius of the circle B using the formula for area of circle and setting up the given area equal to the formula.
Therefore, radius of the circle B is 24 centimeters.
We know that diameter is twice the radius, therefore, diameter of circle B will be 24*2=48 centimeters.
Finally, we can express the circumference of circle using the formula:
Therefore, circumference of the circle B is 150.72 centimeters.
Answer:
The radius is 5.5 mm
Step-by-step explanation:
The diameter is 11 mm
The radius is 1/2 of the diameter
1/2 d =r
1/2(11) =r
5.5 =r
The radius is 5.5 mm
