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
The correct answer is 60cm^2 because the area of a triangle is half base*height -> 30/2*40
-20%
work:
(24-30):30*100=
(24:30-1)*100=
80-100=-20
