length =88cm
breadth=21cm
when it is rolled it becomes cylinder
having circumference 88cm
2πr=88cm
r=88×7/44
r=14
h=21
total surface area of the cylinder =2πr(r+h).
=2×22/7×14(14+21)
=3080cm²
Answer:
Might be wrong but 27. Hope this helps
The height of the all after 2 secs is 86 feet
<h3>Functions and vales</h3>
Given the height in feet above the ground was given by the following function h(t) = -16t^2 + 75t
where:
t is the number of seconds since the ball was punted.
If the value of t = 2s, hence;
h(t) = -16t^2 + 75t
h(2) = -16(2)^2 + 75(2)
h(2) = -64 + 150
h(2) = 86
Hence the height of the all after 2 secs is 86 feet
