How do you do this and what are the answers

scoray [572]

I can answer 1 to 4...
The area of a circle can be found by $\pi r^{2}$ . Reminder: $\pi = 3.14$ (usually used when finding out the area of a circle)

1. $4^{2} = 16$
$\pi *16$ or $3.14 * 16 = 50.24$
$50.24/4=12.56$

2. $6^{2} = 36$
$\pi *36$ or $3.14 * 36 = 113.04$
$113.04/10=11.304$

(Not really sure if this is correct) 3. $2^{2}=4$
$\pi *4$ or $3.14 * 4$
$12.56/2.66666667=11.70999999$

4. $6^{2}=36$
$\pi *36= 113.04$
$113.04/6=18.84$

Determine the slope of the line shown.

marin [14]

Pick 2 points off ur line...it is easier if u pick whole number points

(2,0) and (0,5)
slope formula = (y2 - y1) / (x2 - x1)
now label ur points
(2,0)...x1 = 2 and y1 = 0
(0,5)...x2 = 0 and y2 = 5
now sub and find the slope
slope(m) = (5 - 0) / (0 - 2) = -5/2 <====
