This is a chemistry question but <span>Atoms are made of two distinct particles.
Electrons occupy a single energy level.
Electrons are smaller than protons.
The majority of an atom's mass is in the nucleus.
Protons and neutrons are about the same size. </span>
Each of those angles are Inscribed angles. A useful fact is that the measure of the intercepted arc of an inscribed angle is twice the measure of the angle.
The intercepted arc of ∠C is arc BED. The intercepted arc of ∠E is arc BCD.
m(arc BED) + m(arc BCD) = 2( m∠C + m∠E)
The two arcs combined make u p the entire circle, so the sum of their measures is 360.
360 = 2(m∠C + m∠E)
180 = m∠C + m∠E
The angles are supplementary.
Answer:
90 + 2 = 92
180 - 92 = 88
Angle Q = 88
Step-by-step explanation:
All a triangles, angles should equal to 180.
Answer:
n=6
Step-by-step explanation:
13.5n + 8 = 89
13.5n = 89 - 8
13.5n = 81
13.5n/13.5 = 81/13.5
n = 6
I hope this helps
Answer:
V = 65.19
Step-by-step explanation:
Remark
You need r. You can get it from the circumference of the circular base.
Once you have that, the formula is Area = 1/3 pi r^2 j
Givens
C = 20.236
h = 6 feet
Formulas
C = 2 pi r
Volume = 1/3 pi r^2 h
Solution
Find r from C = 2 pi r
20.236 = 2 * 3.14 * r Combine the right
20.236 = 6.28 * r Divide by 6.28
20.236/6.28 = 6.28 * r / 6.28
3.222 = r
Now that you have r, you can solve for the volume
V = (1/3) pi 3.222^2 * 6 Square r
V = 1/3 * pi * 10.381 * 6 Now multiply through by all, but pi
V = 20.762 pi
V = 65.194
