Question

HELLLPP!!
Which of these has the greatest area? Use for .

rhombus with side lengths: 9 inches, height: 4 inches

triangle with base length: inches, height: 4 inches

circle with diameter: 4 inches

trapezoid with base lengths: 3 inches and inches, height: 6 inches

Answer 1

You have to compute all the areas.. do you know the formulas?

Answer 2

no

Answer 3

circle: \(\pi r^2\), \(r\) is the radius = 1/2 diameter
triangle: side x height / 2
trapezoid: (BASIS + basis) x height / 2
rhombus: let me see

Answer 4

rhombus: side lenght x height.

Answer 5

Okay so now what??

Answer 6

compute it:
circle: \(\pi r^2 = \pi (4/2)^2 = 4\pi \simeq 4\times 3.14 = 12.56\)
triangle: oh a value is missing in your post
trapezoid: a value is missing
rhombus: \(9\times 4 = 36\).

Answer 7

after finding the missing values and computing the areas, simply find which one is the greatest area.

Answer 8

I'm so lost

Answer 9

do you see that in the question you posted on this page, there are numbers missing?
for example for the triangle, we need two values (the basis, the height) in order to compute the height. but the basis' length is missing.
