Help with what though?
jim_thompson5910 is helping me through message but he needed to see these images
I need help with this though Find the area of the triangle. 24 square units 11 square units 12 square units 5.5 square units
Area of a triangle is \[\large A=\frac{1}{2}\times height \times base\] The base is going to be the distance between the two bottom points. The height will be the distance between the middle of the base and the top point.
so the base would be 6?
Correct.
and 5 for height?
so 15?
Close, it would be 4
oops okay thanku!

this is for the 4 circles image A point in the figure is selected at random. Find the probability that the point will be in the part that is NOT shaded.
@LegendarySadist
Do they give you any units, or no?
@jim_thompson5910
no
Well as we can see, the lengths of 2 diameters is the same as the length as one side of the square. If we say that the length of the side of the square is 4, then that means that the diameter of a circle is 1/4th that, or 1. Can you figure out the areas from that?
Im confused with this one too, i keep getting an answer thats not on my multiple choice Find the area of the kite. 190.44 m2 126.96 m2 253.92 m2 380.88 m2
multiply the diagonals, then divide by 2
the diagonal lengths are given in pieces, so you'll have to add them up first
so theres 4 sides to a square 4+4+4+4= 16 and 16/ 1/4= 64 did i do it right?
@jim_thompson5910 all 4 of them?
the longer diagonal is 6.9+13.8 = 20.7
do the same for the other diagonal multiply the diagonals, then divide by 2
so 6.9+13.8= 20.7 9.2+9.2= 18 2/5
my calc isnt letting me put in 2/5 after 18
ok its 380.88/2 = 190 11/25
so 190.44 m2 ?
@LegendarySadist so theres 4 sides to a square 4+4+4+4= 16 and 16/ 1/4= 64 did i do it right?
Area of a square is \[\large A=side^{2}\] and area of a circle is \[\large A=\pi r^{2}\]
so \[4^{2} + 4^{2} + 4^{2} + 4^{2} = 64 ?\]
Where are the 4 squares that you're adding together? What? It's JUST \(4^{2}\)
\[\large 4^{2}=16\] Boom, now we have the area of the square.
\[4^{2}= 16\]
oops
\[16\div \frac{ 1 }{ 4 } = 64\]
Now we find the area of the circle and multiply it by 4. Area of a circle is \(A=\pi r^{2}\) so if we want that times 4 it would look like \[\large A=4\pi r^{2}\] and HOW ARE YOU GETTING 64????
u said the diameter of a circle is 1/4th that? above^
sorry got confused.. what do i put for r?
so 4*3.14*5^2 = 314 could i do that or?
So the diamater of two circles is the side length. So \[\large 2d=side\] Since the radius is half of the diamater, it would be \[\large 4r=side\] The side is 4, as we know, so it would be \[\large 4r=4\] which makes \[\large r=1\]
so 4*3.14*1^2 = 12 14/25
Yeah. Now to find the area of the unshaded region, just do \[\large Area~of~square~~-~~Area~of~circles~=~Area~of~unshaded~region\]
so 16-12 14/25= 86/25
so 25%? or?
To find the chance of getting the unshaded region, so \[\large \frac{Area~of~Unshaded~region}{Area~of~square}\]
\[\frac{ 86 }{ 25 } \div 16 = \frac{ 43 }{ 200 }\]
thats not on my answers though..
In percentage form, it's 21.5% tho
yeah in decimal form its 0.215 so i guess i got confused
should of converted the decimal to percentage oops
thank you!
