In geometry, Heron's formula (sometimes called Hero's formula), named after Hero of Alexandria, gives the area of a triangle by

Ksju [112]

Answer:

The area of ΔABC is 6√6 sq. yards.

Step-by-step explanation:

The area of a triangle using the Heron's formula is:

$A=\sqrt{s\cdot (s-a)\cdot (s-b)\cdot (s-c)}$

Here <em>s</em> is given as follows:

$s=\frac{a+b+c}{2}$

The sides of the triangle ABC are as follows:

AB = 6 yd

BC = 7 yd

CA = 5 yd

Compute the value of <em>s</em> as follows:

$s=\frac{a+b+c}{2}$

$=\frac{6+7+5}{2}\\\\=9$

Compute the area of ΔABC as follows:

$A=\sqrt{s\cdot (s-a)\cdot (s-b)\cdot (s-c)}$

$=\sqrt{9\cdot(9-6)\cdot(9-7)\cdot(9-5)}\\\\=\sqrt{9\times 3\times 2\times 4}\\\\=\sqrt{216}\\\\=\sqrt{36\times 6}\\\\=6\sqrt{6}$

Thus, the area of ΔABC is 6√6 sq. yards.

Five less than one third of a number

yaroslaw [1]

Answer:

$x\frac{1}3 -5$

Step-by-step explanation:

You don't know the number, so you replace it with x.

Since it is one third of x, you multiply x by $\frac{1}{3}$

Then you subtract 5 from the whole thing: $x\frac{1}{3} -5$

The area of a circle is 706.5 square inches. What is the radius? Use 3.14 to approximate pi.

alexdok [17]

What you know is
area=706.5in^2
formula is 3.14*r*r
what to do is set up an equation
706.5=3.14*r*r
after you divide both sides by 3.14 to cancel it out your left with
225=r^2
then you would take the root of both sides to get
r= 15 , -15
