Question
Download Solution PDFSteel is used to make a hemispherical bowl that is 0.37 cm thick. The bowl's inner radius is 6 cm. Find the bowl's outside curved surface area (take \(\pi = \frac{22}{7}\)).
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFGiven::
Inner radius = 6 cm
Thickness = 0.37 cm
Formula used:
Outer radius = Inner radius + Thickness
Curved surface area of the hemisphere = \(2\pi r^2\)
Calculations:
According to the formula,
⇒ Outer radius = 6 + 0.37 = 6.37 cm
⇒ Curved surface area = \(2 \times \frac{22}{7} \times 6.37 \times 6.37 \) = 255.0548 cm2
⇒ Hence, Curved surface area of the hemisphere is 255.0548 cm2
