If a = 2 cm and r = 3.4 cm, find the area of the regular pentagon.
cricket20 [7]

Answer:

Area = 3.4\ cm^{2}

Step-by-step explanation:

Assume a pentagon has equal length where a be the side of the pentagon and r be the apothem of the pentagon.

Given:

Sides of pentagon a=2\ cm

apothem of pentagon r=3.4\ cm

The area of the pentagon formula is given below.

A = \frac{1}{2}\times bh

Where b = length of the base or side

And h = height of apothem

Now, we substitute side and apothem length in above formula.

A = \frac{1}{2}\times 2\times 3.4

A = 3.4\ cm^{2}

Therefore, the area of the pentagon is 3.4\ cm^{2}

At what rate should $1,000 be invested compounded
marishachu [46]

Answer:

14.9%

Step-by-step explanation:

Using the compound interest formula;

A = P(1+r)^t

A is the amount = $2000

P is the principal = $1000

r is the rate

T is the time = 5 years

Substitute the given values into the formula;

2000 = 1000(1+r)^5

2000/1000 = (1+r)^5

2 = (1+r)^5

\sqrt[5]{2} \\ = 1 + r

r = 1.149 - 1

r = 0.149%

Hence the required rate is  14.9%
