A) a bench --- C=2πr, if r=π, then C=2π²=19.74,
if you need to use π=3.14, then C=19.72 ft
cover ---- area =πr²=π³=31.01 ft²
if you need to use π=3.14, then A=30.96 ft²
B) R=2.5r
C=2πR, if R=2.5π, then C=2*2.5π²=5π²=49.35 ft
if you need to use π=3.14, then C=49.30 ft
how much longer = 49.35 -19.74=29.61 ft
Answer:
Slope=1/2
Step-by-step explanation:
Slope=(y2-y1) /(x2-x1)
(-5,2)............x1=-5, y1=2
(1,5)..............x2=1, y2=5
Slope=(5-2)/(1-(-5))
Slope=3/(1+5)
Slope=3/6
Slope=1/2
I'm not sure about this question. There is so many positive integers and try to search it on Google. That might be a lot of integers to count.

Step-by-step explanation:
to make it perpendicular 2/3 becomes -2/3
Answer:
(a) 0.8655
(b)0.8655
Step-by-step explanation:
X is the number of respodents who agree
P(x ≥4), n=12, p=0.45
P(x ≥4)=1-P(x<4)
P(x<4)=P(0 ≤x<4)= P(0 ≤x≤3)=P(x=0,1,2,3)=P(x=0)+P(x=1)+P(x=2)+P(x=3)
P(x ≥4)=1-P(x<4)=1-0.134468=0.8655319
(b)
Y represent those who agree
P(Y≤8), n=12, p=0.45
P(Y≤8)=1-P(Y>8)
P(Y>8)=P(8<Y≤12)=P(9≤Y≤12)=P(Y=9,10,11,12)
Total =0.134468
P=1-0.134468=0.8655319
