Can somebody check my geometry work?

OpenStudy (icalibear):

Points __ and __ are 4 units from K. answer: G and O Which segment is congruent to segment GJ? answer: LO The coordinate of the midpoint of segment NH is __. K

jimthompson5910 (jim_thompson5910):

Points __ and __ are 4 units from K. answer: G and O ----> correct

OpenStudy (icalibear):

Are the other two right? I know this is really simple stuff but I have to get this right lol

jimthompson5910 (jim_thompson5910):

Which segment is congruent to segment GJ? answer: LO this correct, but there are other segments that are congruent to GJ (like HK for instance)

OpenStudy (icalibear):

Yeah, it only asked for one though

jimthompson5910 (jim_thompson5910):

you're doing fine, just got to trust yourself

OpenStudy (icalibear):

:P

jimthompson5910 (jim_thompson5910):

and K is correct for the last one, so they're all correct

OpenStudy (icalibear):

Ok ^.^ thanks

OpenStudy (icalibear):

One more thing if the area of a radius of a circle is 15 in. the area to the nearest tenth is 2,218.4?

OpenStudy (icalibear):

radius not area of a radius

jimthompson5910 (jim_thompson5910):

incorrect

jimthompson5910 (jim_thompson5910):

you use the formula \[Large A = \pi r^2\]

jimthompson5910 (jim_thompson5910):

and you do NOT square pi

OpenStudy (icalibear):

3.14(15) = 47.1 47.1^2 = 2,218.4

OpenStudy (icalibear):

oh its 706.5?

jimthompson5910 (jim_thompson5910):

you square 15, then you multiply it by pi

jimthompson5910 (jim_thompson5910):

yeah 706.5

OpenStudy (icalibear):

ok
