44 square feet
Diameter (4) divided by 2 is radius (2).
SA = 2πr^2 + 2πrh
SA = 2 * 3.14 * 2^2 + 2 * 3.14 * 2 * 3
SA = 2 * 3.14 * 4 + 2 * 3.14 * 2 * 3
SA = 6.28 * 4 + 6.28 * 3
SA = 25.12 + 18.84
SA = 43.96
Round to the nearest tenth.
SA = 44 square feet

Solving for A



Answer:
10⁴ seconds
Step-by-step explanation:
Given that,
A person breathes
in about cubic meters of air per second.
We need to find time taken to breathe 2.5 cubic meters of air.
In 1 sec =
m³ of air breathe
Let in x seconds, 2.5 m³ of air taken by the person.

Hence, in 10⁴ seconds 2.5 m³ of air is taken by the person.
