Question

4. Taking π = 3.14, find the diameters of the circles whose areas are
(1) 2826 m²
(ii) 7.065 mm²
(iii) 254.34 cm²​

Answer 1

Answer:

1) 57.6 m

2) 3 mm

3) 18 cm

Step-by-step explanation:

1) r*r = 2826/3.14 = 831 , r= 28.82  so d=r*2= 57.6 m

2) r*r = 7.065/3.14 = 2.25, r=1.5  so d=r*2= 3 mm

3) r*r = 254.34/3.14 = 81, r=9  so d=r*2= 18 cm

Answer 2

Answer:

Hey mate here's your answer.

Step-by-step explanation:

(1)

πr²=2826

3.14*r²=2826

r²=900

r=30m

Therefore diameter=30*2=60m.

(2)

πr²=7.065

3.14*r²=7.065

r²=2.25

r=1.5mm

Therefore the diameter=1.5*2=3mm

(3)

πr²=254.34

3.14*r²=254.34

r²=81

r=9cm

Therefore the diameter=9*2=18cm.

Hope it helps you.
