29/3=9.66
9.66^2=93.31
But 93.31>83
Therefore the student was wrong
The slope of that line would be:
5,8!
have a great day!
Answer:
Step-by-step explanation:
let coordinates of D are (x,y)
mid point of AC=midpoint of BD
so{ (-3+4)/2,(1+6)/2}={(x+(-1))/2,(y+4)/2}
(1/2,7/2)={(x-1)/2,(y+4)/2}
(x-1)/2=1/2
x-1=1
x=1+1=2
(y+4)/2=7/2
y+4=7
y=7-4=3
so D is (2,3)
Volume = Pi × radius squared × height
Radius = Diameter ÷ 2
= 8 ÷ 2
= 4 cm
Volume = Pi × 4 squared × 12
= Pi × 16 × 12
= 603.1857895...
= 603.19 cm cubed
Note : Pi is approximately equal to 3.14
