Answer:
∠ BCE = 80°
Step-by-step explanation:
∠ BCD = ∠ ABC = 35° ( alternate angles are congruent )
∠ DCE and ∠ CEF are same- side interior angles and supplementary, thus
∠ DCE + ∠ CEF = 180° , that is
∠ DCE + 135° = 180° ( subtract 135° from both sides )
∠ DCE = 45°
Thus
∠ BCE = ∠ BCD + ∠ DCE = 35° + 45° = 80°

For #4, we know V = lwh
We have the values
5184 = 2(18)h
Solve for h
5184 = 36h
144 = h.
for # 3:
we know A = pi r^2
We have
A = 3.14 * 6^2
A = 3.14 * 36
A = 113.04
for #2:
We know C = 2pi *r
C = 2(3.14)(14)
C = 28(3.14)
C = 87.92
for #1:
C = 2pi * r
C = 2(3.14)(26.3/2)
C = 2(3.14)(13.15)
C = 26.3(3.14)
C = 82.582

Each sphere of ice has a radius of 2cm
one tray makes 6 spheres
What is the total volume of ice the tray can make at one time?
Total volume of each sphere is 33.51 cm^3
The tray can hold 6 of these at a time
33.5 * 6
201 cm^3 total volume of ice that the tray can make at one time
Written in pi
64 cm^3
