Question

Is this right I got 18 for the area

Answer 1

#37

Answer 2

recall that the area of a triangle is 1/2 base * height
thus
notice, the internal corners of the triangles in the rhombus, have 45 degrees
whilst the diagonals are perpendicular by definition, meaning 90 degrees

thus so, using the 45-45-90 rule

Answer 3

yup

Answer 4

hyp is 3sqrt2

Answer 5

hmmm wait a sec... actually... yes
3 * 3 = 9 for a half
and 3 * 3 = 9 for the second half, 9 + 9 = 18
yes

Answer 6

This is a 45-45-90 degree triangle which means that the legs are both equal so since one side is 3cm the other will be as well....So we need to figure out both diameters in which we multiply 3 by 2...

\(\Large{3 \times 2 = diameter1=6}\)
\(\Large{3 \times 2 = diameter2=6}\)

In which we input into this equation...

\(\LARGE{A=\frac{1}{2}d1d2}\) Input...

\(\LARGE{A=\frac{1}{2}6(6)}\)simplify...

\(\LARGE{A=\frac{1}{2}36}\) in which we divide by 2...

\(\Huge\color{red}{\frac{36}{2}=18}\)

So yes that would be the answer

Is this right @jdoe0001

Answer 7

oh

Answer 8

thank you

Answer 9

@563blackghost yeap

Answer 10

would simple radical form be 3sqrt6?

Answer 11

I dont know O.o We werent trying to find the square root of 18 so I guess this is how it would be....
