Answer:
Step-by-step explanation:
The formula of a volume of a cone:
r - radius
H - height
We have
r = (7 : 2) in = 3.5 in
H = 4 in
Substitute:
Answer:
-b=11
Step-by-step explanation:
Nothing else is equal to a number except its self
Since you'd didn't specify what place value I'm assuming it's the whole number so the answer is: 80,000,000
We have an equation for the surface area of a rectangular prism:
A= 2 (w*l+ l*h+ h*w)
Plug l= 16 in, w= 12 in, and h= 5 in into the above equation, we have:
A= 2 (12 in*16 in+ 16 in* 5 in+ 5 in* 12 in)= 664 in^(2).
The final answer is 664 in^(2).

Answer: 9/100
Step-by-step explanation:
Probability of people own a cat:
P(cat)=30/100=0.3
Probability of people own a bird:
P(bird)=3/100=0.03
Probability of both own a cat and a bird
P(cat and bird)=(30/100) × (3/100)
=90/1000=9/100=9%
