Answer:
Step-by-step explanation:
Any number equal to or greater than 20 is a solution. 22 would be a solution.
Lateral area of the cone is given by:
LA=πr√(h²+r²)
where:
h=height
r=radius
Given that LA=287.5 yd² and r=(15/2) yds, then the height will be:
287.5=7.5π√(h²+7.5²)
solving for h we get:
(287.5/7.5π)²=h²+7.5²
thus
h²=(287.5/7.5π)²-7.5²
h²=63.1851597
To get the slant height we use Pythagorean theorem.
c²=a²+b²
a²=h², b²=7.5²
thus
c²=h²+7.5²
c²=63.1851597+56.25
c²=119.4351597
c=10.92864~10.9 yards
2a=y-2b
a=y-2b/2
a=y/2 -b
hope this helps !
Hello!
Firstly, let's subtract the one time charge of $100, because we know for sure that Kaya is paying that:
347.50 - 100 = 247.50
Now, divide this by the hourly rate:
247.50 / 45 = 5.5
Kaya rented the limo for 5.5 (five and a half) hours. =)
