Answer:

$231.42

Step-by-step explanation:

Find the tub radius. It is C = 2πr, which here is C = 6.28(5.5 ft ) = 34.54 ft.

The border costs $6.70/ft. Multiply $6.70/ft by 34.54 ft:

($6.70/ft)(34.54 ft) = $231.42

The area of the square is 100 square centimeters. What is the area of the circle?

swat32

Answer:

Since the question is incomplete, see the figure attached and the explanation below.

Explanation:

Since the figure is missing, I enclose the figure of a square inscribed in a circle.

Since the <em>area of a square</em> is the side length squared, you can determine the side length:

Area = (side length)²

100 cm² = (side lenght)²

$side\text{ }length=\sqrt{100cm^2}=10cm$

From the side length, you can find the diagonal of the square, which is equal to the diameter of the circle, using the Pythagorean theorem:

diagonal² = (10cm)² + (10cm)² = 2 × (10cm)²

$diagonal=\sqrt{2\times (10cm)^2}\\ \\ diagonal=10\sqrt{2} cm$

The area of the circle is π (radius)².

radius = diameter/2 = diagonal/2

$area= \pi \times (5\sqrt{2}cm)^2=50\pi cm^2$

$\sqrt[4]{3. \sqrt[4]{432}}$
= $\sqrt[4]{3. \sqrt[4]{2^4.3^3} }$
= $\sqrt[4]{3.2.3^\frac{3}{4}}$
= $3^\frac{1}{4}.2^\frac{1}{4}.3^\frac{3}{16}$
= $3^\frac{7}{16}.2^\frac{1}{4}$
