Answer:
x = 12
Step-by-step explanation:
m<BCF and m<CFE are same-side interior angles.
Same-side interior angles are supplementary. This implies that:
m<CFE + m<BCF = 180°
where,
m<CFE = 11x°
m<BCF = 4x°
Plug in the values
11x + 4x = 180
15x = 180
x = 180/15
x = 12

The volume of a cylinder:
V = πr²H
A diameter is equal 2r (r-a radius), therefore 2r = 10in ⇒ r = 5in.
H = 3r ⇒ H = 3 · 5in = 15in
subitute:
V = π · 5² · 15 = π · 25 · 15 = 375π (in³) ≈ 375 · 3.14 = 1,177.5 (in³)
Answer: V = 1,177.5 in³
Answer:
V≈20.94
Step-by-step explanation:
The formula for solving the volume of a cone is V=πr^2(h/3).
Hope this helps and I hope u have an Amazing day!!
