Question

.A company wants to manufacture 750 hemisherical basins from a thin steel sheet. If the

radius of each basin is 28cm, find the area of steel sheet requiredto manufacture the

above hemispherical bowls.​

Answer 1

Step-by-step explanation:

Given .A company wants to manufacture 750 hemispherical basins from a thin steel sheet. If the  radius of each basin is 28 cm, find the area of steel sheet required to manufacture the  above hemispherical bowls

• Radius of the hemispherical basin r = 28 cm
• We know that surface area of a hemispherical basin = 2 π r^2
•                                                                                        = 2 x 22/7 x 28 x 28
•                                                                                       = 4928 cm^2
• Now surface area of a hemispherical basin = 4928 cm^2
• Therefore steel sheet required for 1 basin will be 4928 cm^2
• Total area of steel sheet required for 750 basins will be 4928 x 750
•                                                                               = 3696000 cm^2
•                                                                                 = 369.6 m^2
