Question

A cylinder whose radius 3.5cm and height 5cm . Find their total surface area and volume

Answer 1

Answer:

Step-by-step explanation:

Answer 2

radius =3.5cm , Height =5cm total surface area of cylinder = 2πr(r+h)= 2×22/7×35/10(35/10+5)=1560/70(35/10+5)=1560/70(85/10)= 156/7+85/10 =13260/70=189.43 radius =3.5 cm,height =5cm Now

$volume \: of cylinder = \pi \: r {}^{2} h = 22 \div 7 \times 35 \div 10 \times 35 \div 10 \times 5 = 110 \times 1225 \div 70 = 11 \times 1225 \div 7 = 13475 \div 7 = 1925$
