Answer:
3 1/8 ft²
Step-by-step explanation:
The area of a parallelogram is equal to the product of its base and its height.
b × h
2.5 × 1.25
= 3.125
The area is 3.125 feet².

Answer:
<h2>
301.593</h2><h2 />
Step-by-step explanation:
surface area = 2πrh + 2πr²
where r = 4 km radius
h = 8 km
<u>plugin values into the formula</u>
surface area = 2πrh + 2πr²
= 2π (4) 8 + 2π (4)²
= 201.062 + 100.531
= 301.593 km²
