Mary wants to buy a small fence place around us semi circular garden demeanor of a semi circle is 18 feet Mary calculus that sh
nevsk [136]

Diameter of a semi circular garden = 18 feet

Radius of the garden :

=  \tt\frac{diameter}{2}

=\tt  \frac{18}{2}

=\tt 9 \: feet

Thus, the radius of the semi circular fence = 9 feet

We know that :

\color{hotpink}\tt \: Circumference \: of \:a \:  semi \: circle \color{plum}=\pi r

Which means, the circumference of Mary's semi circular garden :

=\tt \pi r

(pi value = 3.14)

= \tt3.14 \times 9

=\tt 28.26 \: \:  feet

Thus, the circumference of fence needed for the semi circular garden = 28.26 feet

28.26 can be rounded off to 28.30 and 28.30 is the same as 28.3

Thus, Mary's reasoning is correct.

Therefore, Mary's reasoning is correct which means she needs 28.3 feet of fence to surround her garden.

Find you equation of the line shown
VashaNatasha [74]

Answer:

y=x+6

Step-by-step explanation:

(0,6). y=mx+b or 6=1 × 0+b, or solving for b: b=6-(1)(0). b=6.

(1,7). y=mx+b or 7=1 × 1+b, or solving for b: b=7-(1)(1). b=6.

I inputted two points from the graph and solved them.

Hence the equation would be y=x+6
