Area of a circle is found by multiplying Pi times the radius squared. The radius of a circle is a segment that has its end points on the circle, and on the center of the circle, or you can think of it like, it goes halfway across the circle
Answer:
5.5+7.25−5.5−7.25 = 0
Step-by-step explanation:
To be honest, you shouldn't have to show work for an equation like this. But this is the answer. Hope it helped.
Answer:
The volume of a hemisphere of some radius can be easily found out by calculating just half of the volume of a sphere of the same radius. Volume of hemisphere = 2πr3/3, where r is the radius of the hemisphere
Step-by-step explanation:
1. 4(n+3)=16, n+3=4, n=1
2. m/4+3=24, m/4=21, m=84
1. three added to a number n implies n+3, 4 times that sum is 4 (n+3), to solve divide both sides by 4 then subtract three from both sides.
2. a number divided by 4 means n/4 adding it to three n/4+3, to solve subtract 3 from both sides then multiply both sides by 4
