Question

lHow much material will be required to make 6 ladoos of radius 3.5 cm?

(a) 154 cm3

(b) 539 cm3

(c) 1078 cm3

(d) 2004 cm3​

Answer 1

Step-by-step explanation:

(c) 1078 cm3 is answer............

Answer 2

$\large{\tt{\red{Given}}}$

$\tt{Radius\:of\:one\:ladoo\:=\:3.5cm}$

$\tt{No.\:of\:ladoo\:=\:6}$

$\large{\tt{\red{Formula\:used}}}$

$\underline{\tt{Volume\:of\:sphere\:=\:\dfrac{4}{3}\pi r^{3}}}$

$\large{\tt{\red{Solution}}}$

$\tt {Material\:to\:make\:1\:ladoo\:=\:\dfrac{4}{3}\pi \times(r)^{3}}$

$\tt Material\:to\:make\:1\:ladoo\:\approx\:175\:cm^{3}$

$\tt Material\:needed\:to\:make\:6\:ladoos\:=\:6\:\times\:175$

$\tt{\orange{Material\:needed\:to\:make\:6\:ladoo\:\approx\:1050\:cm^{3}}}$

$\tt{\orange{So,~the~is~option~(C)~1078~cm^{3}}}$
