Question

13.   The area of a triangle with base 19 in. and height 11 in. is _____. Be sure to include units.  (1 point)

zale101 · Answer

Area = b*h/2

zale101 · Answer

B=base
H=hieght

vjordillo · Answer

Substitute the values in this equation $$\frac{ 1 }{ 2 }(b)(h)$$

zale101 · Answer

now, plug in and solve

anonymous · Answer

so i do 19 * 11 and then divide by 2? @Zale101

calculusxy · Answer

Yes. That's right.

zale101 · Answer

the formula says Base X Height divide by 2

zale101 · Answer

what u did was correct, let me know if u got the answer

anonymous · Answer

i got 104.5 i dont think i did it right.@Zale101

anonymous · Answer

@Zale101

zale101 · Answer

Area of a triangle =  base * height /2

= 19 in * 11  in

= 209 in/2

= 104.5 in^2.

zale101 · Answer

correct :)

anonymous · Answer

@Zale101 Thanks for working out the problem with and not just giving me the answer. Can you help me with one more please?

calculusxy · Answer

Not Zale101 though here. But I will try to help :)

@calculusxy ok cool thanks.14.   The area of a circle with a radius of 15 in., to the nearest tenth is _____. Be sure to include units

calculusxy · Answer

A radius is half of the diameter. The formula for findning the area of a circle is: d*3.14=area. D=diametre

vjordillo · Answer

Area of a circle is $$A =\pi r ^{2}$$
then plug in the value of r

calculusxy · Answer

So the radius is 15, meaning that u have to multiply 15*15=225. then 225*3.14=706.858347058. If u round that then it will be 706.9in.
