Answer:

The area of the deck that surrounds the hot tub is 17.9 m².

Step-by-step explanation:

Base of deck = 5 m

Height of deck = 5 m

Area of deck = base*height

= 5*5

= 25 m²

A circular hot tub is placed in the deck whose diameter is 3 m.

Radius = diameter/2

= 1.5 m

Area of the circular hot tub = πr²

= 3.14*(1.5*1.5)

= 7.07 m²

Area of the deck that surrounds the hot tub = Area of deck - Area of tub

= 25 - 7.07

= 17.93 m²

= 17.9 m²

Circle A has a diameter of approximately 20 inches and an area of approximately 300 in2.

Katena32 [7]

Answer:

4. About 2,700 in2

Step-by-step explanation:

The area of a circle ( $A$ ), measured in square inches, is directly proportional to the square of its diameter ( $d$ ), measured in inches. That is:

$A \propto d^{2}$

$A = k\cdot d^{2}$

Where $k$ is the constant of proportionality, dimensionless.

In consequence, the following relationship between circles A and B is obtained:

$\frac{A_{B}}{A_{A}} = \frac{d_{B}^{2}}{d_{A}^{2}}$

The area of the circle B is now cleared:

$A_{B} =\left(\frac{d_{B}}{d_{A}} \right)^{2}\cdot A_{A}$

Given that $d_{A} = 20\,in$ , $d_{B} = 60\,in$ and $A_{A} = 300\,in^{2}$ , then:

$A_{B} = \left(\frac{60\,in}{20\,in} \right)^{2}\cdot (300\,in^{2})$

$A_{B} = 2700\,in^{2}$

Therefore, the correct answer is 4.

Of 6.5 hectoliters of fuel, the private spilled 350 milliliters. how many liters did the private spill?

sergiy2304 [10]

The private spilled 0.35 litres of fuel

<h3>How to calculate the amount of litres spilled ? </h3>

The first step is to convert 6.5 hectolitres to litres

= 6.5 × 100

= 650 litres

Next is to convert millilitres to litres

= 350/1000

= 0.35 litres

Hence the number of litres spilled is 0.35 litres
