Question

20. A joker's cap is in the form of a right
circular cone of base radius 7 cm and the
slant height is 25 cm. Find the area of the Cap

Answer 1

$\huge {\underline {\underline {\mathfrak {Answer}}}}$

The area of the conical cap is $704 \: {cm}^{2}$

$\huge {\underline {\underline {\mathfrak {</strong><strong>E</strong><strong>xplanation}}}}$

Given,

• Radius (r) = 7 cm
• Slant height (l) = 25 cm

Now,

$</strong><strong>TSA</strong><strong> = \pi r(l + r) \\ \: \: \: \: \: \: \: = \frac{22}{7} \times 7 (25 + 7) \\ \: \: \: \: \: \: \: = 22 \times 32 \\ \: \: \: \: \: \: \: = 704 \: {cm}^{2}$

•°• The area of the conical cap is $704 \: {cm}^{2}$

Answer 2

$\huge{\underline{\underline{.........Answer}}}$

The area of conical shape is 704cm^2

$\huge{\pink{\underline{\green{\mathbf{Explanation}}}}}$

$radius = 7 \\ slanting \: height = 25 \\ formula = \pi \: r \: (l + r) \\ \frac{22}{7} \times 7(25 + 7) \\ \\ 22 \times 3 = {704}cm^{2}$
