Here given that r= 0.8
Area of circular glass = area of circle = pi r^2
= 3.14 ( 0.8)^2 = 2.009 square meter
cost of one square meter = 4.60
cost of 2.009 square meter = 4.60 * 2.009 = 9.244
Answer $ 9.244 .
25% discount of $120
=100*0.25
=$25
Answer:
12.5
Step-by-step explanation:
first you do the one in the 40-15 then you add 50 the you divide by 6
Using the shell method, the volume is
Each cylindrical shell has radius 
(the horizontal distance from the axis of revolution to the curve 
); has height 
(the vertical distance between a point on the 
-axis in 
and the curve ).
Compute the integral.
