Answer:
Percentage decrease in surface area =
Step-by-step explanation:
Given: A right circular cylinder has a radius of 6 inches and a height of 4 inches.
To find: percent change in surface area of the cylinder if height and radius are decreased by 10%
Solution:
Original radius of cylinder (r) = 6 inches
Original height of cylinder (h) = 4 inches
Original surface area of cylinder (a) =
New radius of cylinder (R) = inches
New height of cylinder (H) =
New surface area of cylinder (A) =
Decrease in surface area =
Percentage decrease in surface area =
Answer:
I believe that it is $420
Step-by-step explanation:
First convert 30% to a decimal which is .30. Then you multiply 600 and .30 you get 180. Finally, you subtract 180 from 600 and that leaves you with 420.
Since this is a compound interest, we will use this formula: A = P(1+r/n)^n*t
P = $1000 --> the amount that we start with
r = 8% --> this is the rate
n = 4 --> This is because it is compounded quarterly.
t = 5 --> the amount of years
A = 1,000.00(1 + 0.02)^(20)
So our final value after inserting those numbers in the equation is: $1,485.95.
Answer: 40
Step-by-step explanation: Multiply by the reciprocal (flip the fraction 1/4), and the new equation is 10*4, which is 40
