Question

slove this question...
The shape of the solid iron rod is cylindrical it height is 11 cm and the beast diameter is 7 cm then find its volume?
​

Answer 1

GIVEN :

• HEIGHT AND DIAMETER OF CYLINDRICAL SOLID IRON ROD IS 11cm AND 7cm

TO FIND :

• VOLUME OF CYLINDRICAL SOLID IRON ROD

SOLUTION :

RADIUS(R) = DIAMETER / 2 = 7/2 cm

HEIGHT (H) = 11cm

VOLUME = πR^2H

= (22 × 49 × 11 ) / (7 × 4)

= 423.5 Cubic. cm

∴ VOLUME OF THE CYLINDRICAL SOLID IRON ROD = 423.5 cubic.cm

FORMULA USED :

$i) \: radius = \frac{diameter}{2} \\ \\ ii)volume \: of \: cylinder= \pi r {}^{2} h$

HOPE IT HELPS !!!!
