First find the volume of the pipe:
V = 3.14*length*(outsideradius^2 - innerradius^2)
= 3.14 * 10*(2.5^2 - 2^2)
= 70.65 cm^3
Now find the mass using the formula density = mass / volume:
Mass = volume * density
= 70.65 cm^3 * 0.92g/cm^3
= 65 grams
Use the proportion x/15 = 3/5 (height of object/length of shadow) and cross multiply. 5x = 45. divide both sides by three and x=9.
Answer:
105°
Step-by-step explanation:
From the picture, C is the center of the circle.
The chord that passes the center is called a diameter.
Angle x is a central angle which corresponds to the arc of it. So therefore the measure of the arc would be the same as the measure of that corresponding <em>central angle </em>and vice versa.
So if m arc BF = 105°, then x° = 105°
I think it’s A?? Idk just my opinion I’m sorry if it’s wrong
