Answer:
The volume and the curved surface area of the solid formed is and respectively.
Step-by-step explanation:
Given that,
A right triangle with sides 6 cm, 8 cm and 10 cm is revolved about the side 8 cm.
As the triangle is revolved at 8 cm it forms a cone of height 8 cm and radius 6cm.
Height, h = 8 cm
Radius, r = 6 cm
The volume of the solid formed is given by :
The curved surface of the solid formed is :
l is slant height
Hence, the volume and the curved surface area of the solid formed is and respectively.
$7.75+$7.75=$15.50 (He took the taxi 2x)
$0.56(14)+$0.56(7)=$11.76 (14 miles on the way to work, 7 miles on the way home since he only rode half way and walked the other half)
$15.50+$11.76=$27.26
Ryan pays $27.76 for the taxi ride per day.
Answer:
m<B is 48°
Step-by-step explanation:
m<C is already 90°
m<A is 42°
42+90+x=180
132+x=180
x=48°
13 is the answer if I'm correct
