Question

Can someone help me in this question plssss.
The area of a circle, in terms of π, is 54π m2.
Find the value of the radius.
Give your answer as a simplified surd.

Answer 1

Answer:

AREA of circle = πr² { r = radius} -----------(1)

Area of circle = 54π m² {given} -----------(2)

from eq(1) & eq(2), we get

=> πr² = 54π

=> r² = 54π/π

=> r² = 54

=> r = √(54) {after taking root both sides

Hence, the value of radius is √(54) m.
