Cone Volume = (π • r² • h) ÷ 3
radius^2 = (3 * Volume) / (PI * height)
radius^2 = (3 * 12) / (PI * 3)
radius^2 = (36)/ (9.4247779608) 
radius^2 = 3.8197186342 
radius = 1.95

Find the measure of Angle R to the nearest tenth. a. 63.8 degrees b. 67.2 degrees c. 70.9 degrees d. 61.5 degrees

Vikki [24]

The complete question in the attached figure

we know that
tan R°=opposite side angle R/adjacent side angle R
opposite side angle R=72 units
adjacent side angle R=25 units
so
tan R°=72/25
R=arc tan (72/25)---------> R=70.85°-------> R=70.9°

the answer is
R=70.9°
