find the curved surface area and total surface area of a right circular cylinder whose height is 15 cm and the radius of the bas
otez555 [7]

Answer:

CSA = 660cm^2 --- Curved Surface Area

TSA = 968cm^2  --- Total Surface Area

Step-by-step explanation:

Given

Shape: Cylinder

h = 15 -- height

r = 7 --- radius

Solving (a): The curved surface area (CSA)

This is calculated as:

CSA = 2\pi rh

This gives:

CSA = 2 * \frac{22}{7} * 7 * 15

CSA = 2 * 22* 15

CSA = 660cm^2

Solving (b): The total surface area (TSA)

This is calculated as:

TSA = 2\pi r(h + r)

This gives:

TSA = 2 * \frac{22}{7} * 7 * (15 + 7)

TSA = 2 * 22 * (15 + 7)

TSA = 2 * 22 * 22

TSA = 968cm^2

A car was bought for $20,000 and has depreciated at a rate of 10% yearly. Find the price of the car 8 years later.
bogdanovich [222]

Answer:

$4,000

Step-by-step explanation:

10% of $20,000 is $2,000, which means the price of the car is decreasing by $2,000 each year. After 8 years, the price of the car has decreased by $16,000 ($2,000 times 8 years). The totals cost of the car is now $4,000, as it was originally $20,000, but decreased by $16,000. (20,000-16,000=4,000).
