Question

Find the radius of the circular space on which a force of 28 N produces a pressure of 4 Pascal.

Answer 1

Answer:

7/root22

Explanation:

Answer 2

step by step explanation:

relation between pressure, force nd area is-

PRESSURE= FORCE/ AREA

putting all the given values in the formula, we get

4 = 28/ πr^2

r^2 = 28/4π

r^2 = 7/π

( π= 22/7)

r^2 = 49/22

r= √49/22

r= 7/√22
