Answer:
we know that
[the lateral area of a right circular cone]=pi*r*l
where
r--------------> the radius of the circle part of the cone
l--------------> the side (slant height) of the cone
r=6 ft
h=8 ft
Step 1
find the slant height of the cone
which is determined by using Pythagoras, since the cross section is a right triangle.
l² = h²+ r²------------> l²=8²+6²-------> l²=64+36---------> l=10 ft
Step 2
find the lateral area
[the lateral area of a right circular cone]=pi*r*l--------> pi*6*10----> 188.4 ft²
the answer is 188.4 ft²
Answer:
x = 25
Step-by-step explanation:
(4x - 35) = 180 - 115
4x - 35 = 65
4x = 100
x = 25
[Part A]
company A company B
A=3h+75 B=2h+85
definition of variables
A=company A
B=company B
h=number of hours used
[Part B]
company A would charge less for 5 hours
justification
company A company B
A=3(5)+75 B=2(5)+85
A=15+75 B=10+85
A=90 B=90
[Part C]
By using the services of company A instead of company B to rent a truck for three hours you save 7 dollars.
company A: A=3(3)+75 = 9+75= 84
company B: B=2(3)+85 = 6+85 = 91
difference: 91-84= 7
