Question

the volume of a circular iron rod of length one metre is 3850 cm cube root find its radius​

Answer 1

Step-by-step explanation:

here,

vol³= πr²h

3850cm³= πr²(1m)

3850cm³= 22/7 × r² × 100cm

r²= (3850cm²× 7)/(100×22)

r²= 55cm²/220

r²= 5cm²/20

r²= 1cm²/4

r= √(1cm²/4)

= 1cm/2 = 0.5cm
