I already gave you these answers man
Step-by-step explanation:
Volume of a cone (V) = (1/3) · π · r² · h
270 = (1/3) · π · r² · h
810 = π · r² · h
(810)/(π · r²) = h
257.83/r² = h
Answer:
its 75 obviously
Step-by-step explanation:
corresponding angles
angles in a straight line
give me the brainiest
180-105=75
angles in a straight line add upto 180
corresponding angles are equal
