1.	A sol id tot is inJor calindes withaand a Cone at end This Commen diameks 42 m and the heigkt ol the cyedindhical and Cenicala hemispherical Shape at one endthe othePo tions are 10 om and t om Respectively Find the Volumea the lo lid to
Answer» Height of the conical portion = 7 cm and height of the cylindrical portion = 12 cm Radius = Diameter/2 = 4.2/2 = 2.1 cm Volume of the solid toy = Volume of the conical portion + Volume of the cylindrical portion + Volume of the hemispherical portion ⇒1/3πr²h +πr²h + 2/3πr³ ⇒ (1/322/72.12.17) + (22/72.12.112) + 2/322/72.12.1*2.1 ⇒ 679.14/21 + 1164.24/7 + 407.484/21 ⇒ (32.14 cu cm) + (166.32 cu cm) + (19.404 cu cm) ⇒ 217.864 cu cm Like my answer if you find it useful!

Answer»

Height of the conical portion = 7 cm and height of the cylindrical portion = 12 cm

Radius = Diameter/2

= 4.2/2

= 2.1 cm

Volume of the solid toy = Volume of the conical portion + Volume of the cylindrical portion + Volume of the hemispherical portion

⇒1/3πr²h +πr²h + 2/3πr³

⇒ (1/3*22/7*2.1*2.1*7) + (22/7*2.1*2.1*12) + 2/3*22/7*2.1*2.1*2.1

⇒ 679.14/21 + 1164.24/7 + 407.484/21

⇒ (32.14 cu cm) + (166.32 cu cm) + (19.404 cu cm)

⇒ 217.864 cu cm
