3.8
What else can I help you with?
A table is in the shape of a regular decagon with side lengths of 2.5 feet. What is the radius of the decagon Round to the nearest tenth?
You can work out the radius firstly.
What is the area of a regular decagon with an apothem of 3.8 cm and a side length of 2.5 cm?
The apothem and side length are not consistent. That is, a decagon with an apothem of 3.8 cm cannot have a side length of 2.5 cm.If the apothem is 3.8 cm then area = 46.9 cm2 whileif the side length is 2.5 cm then area = 48.1 cm2.The two answers agree at the tens place and so the most accurate answer is 50 cm2 to the nearest 10.
What is the area of a regular decagon with a side length of 7 cm and an apothem of 10.8 cm?
378 cm ^2
What is the area of a regular octagon with a side of 6.5 and an apothem 5?
130 to find the area of any regular polygon, multiply the perimeter by one-half the apothem. This is the same as multiplying the side-lengths by the number of sides by one-half the apothem.
What is the apothem of a regular hexagon with a radius of 12 centimeters Round to the nearest tenth?
10.4 cm
What is the area of a regular decagon whose side is 1.2 and whose apothem is 1.85?
Area of a regular polygon equals to the one half of the product of its perimeter with the apothem. So we have: A = (1/2)(a)(P) Since our polygon has 10 sides each with length 1.2, the perimeter is 12 910 x 1.2). Substitute 12 for the perimeter, and 1.85 for the apothem in the area formula: A = (1/2)(a)(P) A = (1/2)(1.85)(12) A = 11.1 Thus, the area of the decagon is 11.1.
How lines of symmetry does a decagon have?
None are guaranteed.If it is a regular decagon (convex, with all side lengths equal and all angle measures equal), then there are 10 lines of symmetry.
To the nearest degree what is the measurement of each exterior angle of a regular decagon?
36 degrees
What is an apothem of a regular polygon?
An apothem is a line segment from the center of a regular polygon to the midpoint of a side.
Is the decagon a regular?
Any Polygon can be a regular figure, if the figure has all straight sides and edges, with all the same length. If the decagon had all straight edges, sides, and same lengths of sides, it would be a regular figure. Otherwise, it would not, and would be an irregular Decagon. * * * * * That is not a correct answer. Any polygon, by definition MUST have all straight sides (which are the same as edges). What makes a polygon regular is that all the sides are the same length AND that all the interior angles are the same measure. Both these conditions must be met.
The shapes on a soccer ball include a regular pentagon with an apothem of 3.5 cm. What is the area of the regular pentagon Round to the nearest whole number?
45 cm
How do you form up a 24 ft decagon?
With the information given it is not possible. Does 24 ft refer to a length of a side, the longest side, the shortest side, a diagonal, an apothem? Knowing the answer to that question can only help if the decagon is regular - and on the basis of the question, there is no reason to assume regularity.
