Answer:
Step-by-step explanation:
Sum of all angles of triangle = 180°
6p + 6p + 3 p = 180
15p = 180
p = 180/15
p = 12
Angles are:
6p = 6*12 = 72°
3p = 3*12 = 36°
Angles are: 72°, 72° , 36°
Answer:
25.12 inch³
Step-by-step explanation:
The volume formula for a cone is 1/3 πr²h
sub in the numbers to get the volume
1/3 x 4 x 3.14 x 6 = 25.12
N^2.....because this is the product of n and itself, not the sum
20/25 as a decimal is 0.8
