Answer:

Step-by-step explanation:

The formula for determining the area of a circle is expressed as

Area = πr²

Where

π is a constant whose value is given as 3.14.

r represents the radius of the circle.

From the information given,

Diameter of the flowerbed is 3 meters.

Radius = diameter/2

Radius of flowerbed = 3/2 = 1.5 meters.

Since the flower bed is semi circular , the area would be divided by 2. Therefore

Area = 1/2 × 3.14 × 1.5²

= 3.5325

Approximately 3.5 m² to 1 decimal place

Answer:

3.5 m^2

Step-by-step explanation:

If the shape is half of a circle, you will be using this formula: A = \frac{1}{2} π r^2

Your radius is half of the diameter. r = d/2 = 3/2 = 1.5

Substitute r = 1.5 into the formula.

A = \frac{1}{2} π 1.5^2

A = \frac{1}{2} (3.14) 1.5^2

Use your calculator to find the answer and round your answer.

3.5

How do I simplify the n^-6*n^3 topic "Negative and Zero Exponents"
Alchen [17]
Since you’re multiplying n^-6 and n^3, you can add the exponents: -6+3 = -3

n^-6 * n^3 = n^-3

If you need to finish without having a negative exponent in your answer, then remember a negative exponent means that factor is on the wrong side of the fraction.

n^-3 = n^-3 / 1 = 1/n^3

when the factor moves to the other side of the fraction, the side of the exponent changes.
