It is: 4*pi*11.5squared = 529*pi square feet
Area = 415.48 ft2
To calculate the surface area of a cone, you need the slant height (l), radius (r), and the height (h). Given the diameter of 18 cm, the radius is 9 cm (18 cm / 2). The surface area ( A ) is given by the formula ( A = \pi r (r + l) ). Substituting the values, ( l = 23 ) cm and ( r = 9 ) cm, the surface area is approximately ( A \approx 3.14 \times 9 \times (9 + 23) \approx 3.14 \times 9 \times 32 \approx 907.2 , \text{cm}^2 ).
A circle with a 23 inch diameter has am area of 415.4756 sq inches (to 4 dp).
To determine the square footage of the surface area of a 55-gallon barrel, you first need to know its dimensions. A standard 55-gallon barrel is typically about 23 inches in diameter and 35 inches tall. The surface area can be calculated using the formula for the surface area of a cylinder, which is approximately 15.5 square feet.
A circle with a radius of 11.5 miles has an area of 415.48 square miles.
The surface area of a sphere with a diameter of 2.7 inches is about 23 square inches.
First find the radius by dividing 23 by 2*pi which works out as 3.660563691 Surface area of the sphere = 4*pi*3.6605636912 = 168.3859298 or about 168 square mm
Area = 0.25*π*diameter2 or π*radius2 Diameter = 23 units gives an area of 415.48 square units

Area = pi*23 squared = 1661.902514 or 1662 square cm rounded
Area = pi*r2r(radius) = diameter/2Radius = 23 cm/2= 11.5 cm-----------------now,Area = pi(11.5 cm)2= 415.5 cm2=========
Area = pi*11.52 = 415.476 square units rounded to 3 decimal places
Entire surface area: (2*pi*121)+(22*pi*23) = = 748*pi square inches
A sphere doesn't really have a length, but if 4 inches is its diameter, then you use the equation4/3πr3Which means, 4/3 times pi (3.14) times the radius of the sphere cubed.To find the radius in this case, you divide the diameter by 2:4 / 2 = 2Then you substitute 3.14 in the equation for π, and 2 for r to get:4/3(3.14)(23)And finally, you solve:4/3 x 3.14 x 23 = 33 37/75 or 33.493
