Steps:
Given that Base radius(r) = 28 in and height(h) = 97 in
Surface Area of a Cone = $(π⋅(Radius))$⋅($(Radius)$ + $\sqrt{(Radius)^2+(Height)^2}$)
Substitute the values of the radius r = 28 in and height h = 97 in into the formula. Pi (π) is approximately equal to 3.14 .
$(π⋅(28))$⋅ $(28$ + $\sqrt{(28)^2 + (97)^2})$
Move 28 to the left of π.
$(28π)$⋅$ (28$ + $\sqrt{(28)^2 + (97)^2}$
Simplify each term
Raise 28 in to the power of 2 and 97 to the power of 2
$(28π)$⋅$ (28$ + $\sqrt{(784.0) + (9409.0)}$ in
Add 784.0 in and 9409.0 in
$(28π)$ in⋅$ (28$ + $\sqrt{(10193.0)}$ in
Multipy 28π in and 28 in
784.0π in + (28π . $\sqrt10193.0$)in
Put the value of $\sqrt10193.0$ = 100.9603883 in formula
784.0π in + (28π . 100.9603883) in
Mulitply the 28π and 100.9603883
784.0π in + (2826.8908716π)
Add 784.0π in and 2826.8908716π in
The result can be shown in multiple forms
