Answer:
V = 255.98189 pi
SA = 172.64114π
Step-by-step explanation:
The first thing to do is find the radius.
the measure of angle AKO = 1/2 the measure of angle AKB
m< AKO = 12.5 degrees
Now use trig to find AO (aka the radius)
tan(12.5) = AO/25
AO = 25* tan(12.5)
<em>I'm leaving it like this to get a more accurate number</em>
Now to find the volume
the volume of a cone is pir^2h/3
plugging everything in we get:
pi(25*tan(12.5))^2 * 25/3
which is about <u>255.98189 pi</u>
Now for surface area
(this is the moment I realize symbols exist)
SA = πr(r+√h²+r²)
plugging everything in we have
π(25tan(12.5))((25tan(12.5)+√625+(25tan(12.5))^2)
<em>I know it looks like a lot but that's mainly because I left the radius as 25tan(12.5)</em>
The Surface Area is about <u>172.64114π</u>
Answer: 5/6
Change 1/2 into 3/6 and 1/3 into 2/6 and add them together.
1. 10 minutes
2. The starting point
3. the time is the same but horse B did one extra mile
Answer:
1. a^mn= (a^m)^n
2. a^m+n= a^m • a^m
3. 1= a^0
4. a^m • b^m = ab^ m
5. 1/a^n = (a)^m
Step-by-step explanation:
^ means exponent
• means multiply
10/40 or 1/4 is the rest of the amount needed to fill the tank up hope I helped.
