Circumference Formula: 2pi x r

Radius = 20.5

Plug it in:

2(3.14) x 20.5

6.28 x 20.5 = 128.74

Then, convert to pi terms.

128.74 = 41 pi

Therefore the circumference of a circle with a radius of 20.5m is 41pi.

Prudence is creating a garden in her backyard. She wants it to be the shape of an equilateral triangle with sides of length 20 f
algol [13]

Answer:

The area of the triangular garden is 173\ ft^{2}  

Step-by-step explanation:

we know that

The equilateral triangle has three equal sides and three equal internal angles (the measure of each internal angle is 60 degrees)

The area of a triangle applying the law of sines is equal to

A=\frac{1}{2}(a)(b)sin(C)

In this problem we have a equilateral triangle

therefore

a=b=20\ ft

C=60\°

substitute

A=\frac{1}{2}(20)(20)sin(60\°)

A=\frac{1}{2}(20)(20)\frac{\sqrt{3}}{2} \\ \\A=100\sqrt{3}\ ft^{2}\\ \\A=173\ ft^{2}
