First you convert the percentage into a decimal. 18% to 0.18, then you multiply that decimal to the price of the item being discounted and bam, you have your price.

Hey Gary!

The volume of a cylinder is PiR^2h, or 3.14(r^2)h.
Let's define our measures.
Pi is 3.14 (simplified). However, our answer is requested in terms of Pi.
Our radius is 5.
Our height is 14.
Let's plug in our numbers.

5^2 • 14 • Pi
5^2 = 25
25 • 14 = 350.

350Pi is our answer.
However, rememver that we need to end our answer in units cubed, as we are using a 3-dimensional figure. Our answer is 350Pi in^3.
Your answer is B.)

I hope this helps!

The radius of a circle is 11 miles. What is the circle's area?<br> Use 3.14 for a.
Y_Kistochka [10]
The circles area would equal 380.13 miles

Area=pi (or 3.14) times the radius to the second power. [A=3.14r(2)]

Area = length x height divide 2
so = (6x6)/2 - (3x2)
= 12 cm square

Answer:

\boxed{ \text{1. 59.44 in}^{2} \text{;  2. 352.7 in}^{2} \text{; 3. 471.6 in}^{2}}

Step-by-step explanation:

1. Area of base

The radius given is that of the circumcircle.

The general formula for the edge length a  of a regular polygon is

a = 2Rsin(π/n)

So,

a = 2 × 5 × sin(π/5) = 10sin0.6283 = 10 × 0.5878 = 5.878 in

The general formula for the area of a regular polygon is

A = ¼na²cot(π/n)

So,

A = ¼ × 5 × 5.878²cot(π/5) = ¼ × 5 × 5.878² × 1.376 = 59.44 in²

2. Lateral area

The general formula for the lateral area L of regular prism is

L = nah

So,

L = 5 × 5.878 × 12 = 352.7 in²

3. Total area

Total surface area = lateral area + 2×base area

S = L + 2B = 352.7 + 2 × 59.44 = 471.6 in²

\boxed{ \text{B = 59.44 in}^{2} \text{; L = 352.7 in}^{2} \text{; S = 471.6 in}^{2}}

What is the area of the polygon?
Evgesh-ka [11]
Area = Area of Rectangle + Area of Triangle
Area = (bh) + (1/2bh)
Area = (9 * 2) + (1/2 * 9 * 6)
Area = 18 + 27
Area = 45 units squared
