Surface Area of a Cone 85 centimeters by 56 centimeters Calculator

The surface area of a cone is equal to the area of the base plus the area of the cone. If the cone Radius 85 centimeters by height 56 centimeters is 49853.9834169 centimeters².

Steps:

Given that Base radius(r) = 85 cm and height(h) = 56 cm

Surface Area of a Cone = $(π⋅(Radius))$⋅($(Radius)$ + $\sqrt{(Radius)^2+(Height)^2}$)

Substitute the values of the radius r = 85 cm and height h = 56 cm into the formula. Pi (π) is approximately equal to 3.14 .

$(π⋅(85))$⋅ $(85$ + $\sqrt{(85)^2 + (56)^2})$

Move 85 to the left of π.

$(85π)$⋅$ (85$ + $\sqrt{(85)^2 + (56)^2}$

Simplify each term

Raise 85 cm to the power of 2 and 56 to the power of 2

$(85π)$⋅$ (85$ + $\sqrt{(7225.0) + (3136.0)}$ cm

Add 7225.0 cm and 3136.0 cm

$(85π)$ cm⋅$ (85$ + $\sqrt{(10361.0)}$ cm

Multipy 85π cm and 85 cm

7225.0π cm + (85π . $\sqrt10361.0$)cm

Put the value of $\sqrt10361.0$ = 101.7889974 in formula

7225.0π cm + (85π . 101.7889974) cm

Mulitply the 85π and 101.7889974

7225.0π cm + (8652.0647825π)

Add 7225.0π cm and 8652.0647825π cm

The result can be shown in multiple forms
