Answer:

She needs 301.8 in² of tissue paper.

Step-by-step explanation:

In order to calculate the amount of tissue paper she needs to make 21 hats, we need to find the area of each hat and multiply it by the total number of hats she wants to make.

Since the Vietnamese conical hats are hollow and don't have a base, we need to find the area of the it's lateral walls, this is given by the following expression:

lateral area = pi*r*l

r = d/2 = 16/2 = 8 in

We were given the height, but we need the slant height, therefore:

l = sqrt(r² + h²) = sqrt(8² + 9²) = sqrt(64 + 81) = sqrt(145)  = 12.041 in

Then the lateral area is:

lateral area = pi*8*12.0141 = 301.8 in²

She needs 301.8 in² of tissue paper.

What is the answer to (6+4)tothe3power-1tothe8power
Ipatiy [6.2K]

Hey there!

\huge\boxed{(6 + 4)^3 - 1^8}

\huge\boxed{= 10^3 - 1^8}

\huge\boxed{10^3}

\huge\boxed{= 10\times10\times10}

\huge\boxed{= 100\times10 }

\huge\boxed{= 1,000}

\huge\boxed{1^{8}}

\huge\boxed{= 1\times1\times1 \times 1 \times 1 \times 1 \times 1 \times 1}

\huge\boxed{= 1 \times 1 \times 1 \times 1}

\huge\boxed{= 1\times1}

\huge\boxed{= 1}

\huge\boxed{1,000 - 1}

\huge\boxed{= 999}

\huge\text{Answer: \textsf{999}}

\huge\text{Good luck on your assignment \& enjoy your day!}

For fun question
ZanzabumX [31]
Consider the function f(x)=x^{1/3}, which has derivative f'(x)=\dfrac13x^{-2/3}.

The linear approximation of f(x) for some value x within a neighborhood of x=c is given by

f(x)\approx f'(c)(x-c)+f(c)

Let c=64. Then (63.97)^{1/3} can be estimated to be

f(63.97)\approxf'(64)(63.97-64)+f(64)
\sqrt[3]{63.97}\approx4-\dfrac{0.03}{48}=3.999375

Since f'(x)>0 for x>0, it follows that f(x) must be strictly increasing over that part of its domain, which means the linear approximation lies strictly above the function f(x). This means the estimated value is an overestimation.

Indeed, the actual value is closer to the number 3.999374902...
