Steps:
Given that Base radius(r) = 9 ft and height(h) = 7 cm
Surface Area of a Cone = $(π⋅(Radius))$⋅($(Radius)$ + $\sqrt{(Radius)^2+(Height)^2}$)
Substitute the values of the radius r = 9 ft and height h = 7 cm into the formula. Pi (π) is approximately equal to 3.14 .
Unit Conversion of 7 cm = 0.2296588 ft
7 Centimeters is 0.2296588 foot
To convert Centimeters to Feet
we know that, 1 Centimeter = 0.032809 Feet or
1 Centimeter = 1/30.48 Feet
To convert Centimeters to Foot, multiply the centimeter value by 30.84.
Result in Foot: 7 × cm/30.84 × ft/cm
Cancel The Comman factor of cm
Result in Foot: 7/30.84 ft
DIvide the 7 by 30.84
Result in Feet: 0.2296588 feet
∴ 7 Centimeters = 0.2296588 foot
$(π⋅(9))$⋅ $(9$ + $\sqrt{(9)^2 + (0.2296588)^2})$ ft
Move 9 to the left of π.
$(9π)$⋅$ (9$ + $\sqrt{(9)^2 + (0.2296588)^2}$
Simplify each term
Raise 9 ft to the power of 2 and 0.2296588 to the power of 2
$(9π)$⋅$ (9$ + $\sqrt{(81.0) + (0.0527432)}$ ft
Add 81.0 ft and 0.0527432 ft
$(9π)$ ft⋅$ (9$ + $\sqrt{(81.0527432)}$ ft
Multipy 9π ft and 9 ft
81.0π ft + (9π . $\sqrt{ 81.0527432 }$) ft
Put the value of $\sqrt{ 81.0527432 }$ = 9.0029297 in formula
81.0π ft + (9π . 9.0029297) ft
Mulitply the 9π and 9.0029297
81.0π ft + (81.0263673π)
Add 81.0π ft and 81.0263673π ft
The result can be shown in multiple forms
Exact Form
Area = 162.0263673π ft
∴ Surface Area of Cone 9 ft by 7 cm is 162.0263673π ft2
Decimal Form
508.7627933 ft2
∴ Surface Area of Cylinder 9 ft by 7 cm is 508.7627933 ft2
or
Unit Conversion of 9 ft = 274.32 cm
9 Foot is 274.32 Centimeters
To convert Foot to Centimeters
we know that, 1 Foot = 30.480 Centimeters
To convert Foot to Centimeters, multiply the foot value by 30.480
Result in Centimeters: 9 ft × 30.480 × cm/ft
Cancel The Comman factor of ft
Result in Centimeters: (9 x 30.480 cm)
Multiply 9 into 30.480
Result in Centimeters: 274.32 Centimeters
∴ 9 Foot = 274.32 Centimeters
$(π⋅(274.32))$⋅ $(274.32$ + $\sqrt{(274.32)^2 + (7)^2})$ cm
Move 274.32 to the left of π.
$(274.32π)$⋅$ (274.32$ + $\sqrt{(274.32)^2 + (7)^2}$
Simplify each term
Raise 274.32 cm to the power of 2 and 7 to the power of 2
$(274.32π)$⋅$ (274.32$ + $\sqrt{(75251.4624) + (49.0)}$ cm
Add 75251.4624 cm and 49.0 cm
$(274.32π)$ cm ⋅ $ (274.32$ + $\sqrt{(75300.4624)}$ cm
Multipy 274.32π cm and 274.32 cm
75251.4624π cm + (274.32π . $\sqrt{ 75300.4624 }$) cm
Put the value of $\sqrt{75300.4624}$ = 274.4092972 in formula
75251.4624π cm + (274.32π . 274.4092972) cm
Mulitply the 274.32π and 274.4092972
75251.4624π cm + (75275.958413π)
Add 75251.4624π cm and 75275.958413π cm
The result can be shown in multiple forms
