23) 17/30
41) 3/10 because 3/10 + 7/10 = 10/10 or 1.
The formula for finding the area of a triangle is: base*height*1/2
So, if we use this information....
4.2*5.5*1/2=11.55
Area=11.55
Answer:
Step-by-step explanation:
volume= (pi)(radius^2)(h)
252(pi)=(pi)(radius^2)(7)
divide both sides by pi
252=(radius^2)(7)
divide both sides by 7
36=(radius^2)
square root each side
6=radius
