Ne4ueva [31]

Answer:

a

Step-by-step explanation:

The base angles PHJ and PJH are congruent , meaning ΔaPHJ is isosceles and so

HP = JP, thus

3x - 6 = x + 2 ( subtract x from both sides )

2x - 6 = 2 ( add 6 to both sides )

2x = 8 ( divide both sides by 2 )

x = 4

Hence

HP = 3x - 6 = (3 × 4) - 6 = 12 - 6 = 6 → a

Star Wars land encompasses an area of 14.0 acres. [1.00 acre = 4046.86m2]. If Star Wars land were made into a circle, what would
Free_Kalibri [48]

Answer:

<h3>The answer is 134.29 m</h3>

Step-by-step explanation:

First of all we need to convert 14.0 acres to m²

1.00 acre = 4046.86 m²

14.0 acres = 14 × 4046.86 = 56656.04 m²

Area of a circle = πr²

where

r is the radius

To find the radius substitute the value for the area into the above formula and solve for the radius

That's

56656.04 = \pi {r}^{2}

Divide both sides by π

We have

{r}^{2}  =  \frac{56656.04}{\pi}

Find the square root of both sides

r =  \sqrt{ \frac{56656.04}{\pi} }

r = 134.29139

r = 134.29 m to 2 decimal places

Hope this helps you
