75.40 cm²
Step-by-step explanation:
SA = 2πrh + 2πr²
SA = 2π(2)(4) + 2π(2)²
SA = 50.27 + 25.13
SA = 75.40 cm²

Answer:
-3/2
Step-by-step explanation:
the slope of a line is expressed as ratio y/x showing how many units y changes, when x changes a certain number of units.
so, going from A to B, x changes 4 units (from -3 to +1), and y changes 6 units (down, from +3 to -3). that makes the y change negative.
so, the slope is
-6/4 = -3/2
The statements with their relation to 0 are:
- Oliver owes his sister $27.
-27
- A building is 38 feet tall.
27
- Erica jumped 2.7 feet above ground.
2.7
- The scuba diver was 38 feet below sea level.
-38
- The basement is 8.3 feet below ground.
-8.3
Statements that represent positions above the sea level are illustrated using the positive sign, while positions below the sea level are represented using the negative sign.
The above highlights imply that the following statements would be represented with positive sign:
- A building is 38 feet tall.
- Erica jumped 2.7 feet above ground.
This is so, because height and positions above the ground are above the sea level
Also, the following statements would be represented with negative sign:
- Oliver owes his sister $27.
-27
- The scuba diver was 38 feet below sea level.
-38
- The basement is 8.3 feet below ground.
-8.3
This is so, because debt and positions below the ground are below the sea level
