Question

the area of circle is 140m² find the radius and circumference of a circle

Answer 1

area of circle = pier^2
140 = 22/7× r^2
140×7/22 = r^2
70×7/11 = r^2
490/11 = r^2
underoot 490/11 = r
circumference = 2 pir r
2 × 22/7× underoot 490/11
solve it plz

Answer 2

Area of circle = πr²

140 = 22/7×r²

140×7/22 = r²

√44.54 = r

3.76 cm = r



perimeter of circle = 2πr

2×22/7×3.76

= 23.83 cm
