Step-by-step explanation: adding and multiplecation
Answer:
a. 12(Nm)
b. anticlockwise
Step-by-step explanation:
Moment = force applied * distance
Congruent sides have congruent angles so
w=70
Triangle angles =180 so
70+70+x=180
140+x=180
-140 both sides
x=40
supplimentary angles (angles that make up a line) =180 so
w+y=180
70+y=180
-70 both sides
y=110
triangle angles =180 so
110+25+z= 180
135+z=180
-135 both sides
z=45
w=70
x=40
y=110
z=45
Assuming you meant inches^3, V=4/3pir^3, substituting gives 28526=4/3pir^3 which simplifies to (3)(28526)/(4pi) which is equal to 6810 taking the cube root gives us the radius, 18.95
