Lateral, means 'side'. So basically they want us to find out the surface area of the can, excluding the top and the bottom.

To solve for the lateral surface area, we multiply the height of the paint can by the circumference of the top circle. We know the height is 7 1/2 in but we need to solve for the circumference.

C=πd
C=6 5/8π in

Surface Area=7 1/2*6 5/8π=49 11/16π in² or 156.097in²

Answer= 49 11/16π in² or 156.097in²

Nathan opens a new savings account and makes an initial deposit of $400.
AfilCa [17]

Answer:

The answer to the first one is 6

Step-by-step explanation:

If the time frame given is 9 months, then we can find that 9 months is 3/4 of a year. 3/4 x 2% = 0.015.     0.015 x 400 = 6. He would have made 6 dollars in 9 months.

Answer the the second one:

4.5% x 5 (years) = 0.225.     0.225 x 10,000 = 2,250. Since this is a car loan and not a bank interest for example, we add it to the total cost. I'm pretty sure its the third one.

Step-by-step explanation:

The triangle above is a right angled triangle ; and can be solved using trigonometric relation :

Using :

Sin 45 = opposite / hypotenus

Opposite = y ; hypotenus = 8

Sin 45 = y/8

y = sin 45 * 8

y = 5.66 units

Side length x ;

Sin 45 = opposite / hypotenus

Sin 45 = x / 8

x = sin 45 * 8

x = 5.66 units
