Step-by-step explanation:

The area of the carpet is 18 * 14 = 252 sq. ft. In one sq. yard there are 3 * 3 = 9 square feet so 252 / 9 = 28 sq. yards. That means you pay 28 * 4 = $112.

One of the legs of right triangle measures 16 cm and the other leg measures 2 cm.

Pavlova-9 [17]

Answer:

16.1 cm (nearest tenth)

Step-by-step explanation:

<u>Pythagoras’ Theorem</u>

$a^2+b^2=c^2$

(where a and b are the legs, and c is the hypotenuse, of a right triangle)

Given:

a = 16 cm
b = 2 cm

Substitute the given values into the formula and solve for c:

$\implies 16^2+2^2=c^2$

$\implies 256+4=c^2$

$\implies c^2=260$

$\implies c=\sqrt{260}$

$\implies c=2\sqrt{65}$

$\implies c=16.1 \sf \: cm\:(nearest\:tenth)$

Calculate the area of this figure to the nearest hundredth. use 3.14 to approximate pi

zaharov [31]

Answer:

49.132 m²

Step-by-step explanation:

Area of a triangle=1/2(base×height)

Area=1/2(6×8)

Area=24 m²

Now

Area of semi circle=πr²/2

Area=(3.14)(8÷2)²/2

Area=(3.14)(4)²/2

Area=(3.14)(16)/2

Area=50.265/2

Area=25.132 m²

Now

Total area=area of triangle+semi-circle

Total area=24+25.132

Total area=49.132 m²
