Regular pentagon of side 10 cm Calculate the area of pentagon?
The area of a pentagon of side length t is given by the formula t2 (sqrt 25 + 10 (sqrt 5)) / 4, or 5t2 tan (54o) / 4. In this case, a pentagon with one side of 10cm has an area of 102 (sqrt 25 + 10 (sqrt 5)) / 4 = 172.05 cm2 (accurate to two decimal places).
What is the perimeter of a regular pentagon with 9cm sides?
To find the perimeter of a regular pentagon with 9cm sides, you would multiply the length of one side by the total number of sides. In this case, 9cm x 5 sides = 45cm. Therefore, the perimeter of a regular pentagon with 9cm sides is 45cm.
If a 2 cm and r 3.4 cm find the area of the regular pentagon Round the answer to one decimal place?
27.50
What is the perimeter of a regular pentagon with sides measuring 4 cm?
Pentagon means five sides. If one side is 4cm, then the perimeter which is the total length of all the sides is 4cm multiplied by 5 equals to 20 cm.
What is the perimeter of a regular pentagon if the length of one side is 13 feet?
If the pentagon is 'regular', we can ignore the digestive implications and focus onthe geometric ones, namely, that each of its five sides has the same length. Sinceone of them is 13 feet long, they all are, and the perimeter is 13 x 5 = 65 feet.
Regular pentagon of side 10 cm Calculate the area of pentagon?
The area of a pentagon of side length t is given by the formula t2 (sqrt 25 + 10 (sqrt 5)) / 4, or 5t2 tan (54o) / 4. In this case, a pentagon with one side of 10cm has an area of 102 (sqrt 25 + 10 (sqrt 5)) / 4 = 172.05 cm2 (accurate to two decimal places).
One side of a regular pentagon measures 4 inches what is the total length of the sides of the pentagon?
20
What is the perimeter of a penatgon?

What is the perimeter of a regular pentagon is 17cm what is the length of one side?
A regular pentagon has 5 equal length sides. So 17/5 = 3.4 cm per side.
What is the perimeter of a regular pentagon if one side is 5cm?
25 cm
What is the area of a regular pentagon given the apothem of 4?
The area ( A ) of a regular pentagon can be calculated using the formula ( A = \frac{1}{2} \times \text{Perimeter} \times \text{Apothem} ). For a regular pentagon with an apothem of 4, we first need the perimeter. The perimeter ( P ) can be found using the formula ( P = 5s ), where ( s ) is the length of one side. However, without knowing the side length, we can use the relationship between the apothem and side length in a regular pentagon, leading to the area being ( A = \frac{5 \times s \times 4}{2} ). Assuming ( s ) as 4 (for simplicity), the area would be ( A = 40 ).
How many sq ftin a 10'x10' pentagon?
To find the area of a regular pentagon, you can use the formula: ( \text{Area} = \frac{1}{4} \sqrt{5(5 + 2\sqrt{5})} s^2 ), where ( s ) is the length of a side. For a 10'x10' pentagon, you first need to determine the length of one side. In a regular pentagon, the side length can be derived from the geometric dimensions, but typically, a pentagon with a 10-foot perimeter would have a side length of 10/5 = 2 feet. Plugging this into the formula gives an area of approximately 6.88 square feet.
What is the perimeter of an pentagon?
5 x the length of one side. * * * * * That would be true if the pentagon were regular. However, there is nothing in the question to indicate that it is a regular pentagon and so nothing to justify that assumption.
What is the perimeter of a regular pentagon with one side measuring 5 centimeter?
25
How do you find the perimeter of a regular pentagon if you know the length of one side?
Multiply the known length by 5, because the sides are all the same length on a regular pentagon and a pentagon has 5 sides.
How many axes of symmetry does a pentagon have?
it has six three on one side three on the other* * * * * No it does not.An ordinary pentagon has none. It can have 1 or, if it is a regular pentagon, 5.
What is the length of one side of a regular pentagon if its perimeter is 205 mm?
41 mm
