A circular tablecloth has a diameter of 48 centimeters. Martel wants to sew a decorative braid around the tablecloth. What is ci

Anit [1.1K]

Hello!

To solve this you use the equation to find the circumference of a circle which is

$C = 2 \pi r$

C is circumference
r is radius which is half the diameter

Put in the values you know and 3.14 for pi

C = 2 * 3.14 * 24

Multiply

C = 150.72

The answer is 150.72 centimeters

Hope this helps!

Lagrange Multiplier Million Dollar question. Anybody please Use the method of Lagrange multipliers to find the max and min value

We are given the equation: g(s,t) = t^2 e^s

Which is subject to the constraint: s^2 + t^2=3

The points (x,y) that will maximize g(s,t) will be the points that will satisfy the equation ∇f(x, y, z) = λ∇g(x, y, z), therefore:

2 t e^s = λ (2 t), so e^s = λ --> 1

t^2 e^s = λ (2 s) --> 2

s^2 + t^2 = 3 -->3

To solve this problem, note that λ cannot be zero by equation 1 since e^s can never be zero. Therefore plug in equation 1 to 2:

t^2 e^s = (e^s) (2 s)

t^2 = 2 s --> 4

Plug in equation 4 to 3:

s^2 + 2s = 3

By completing the square:

s^2 + 2s + 1 = 4

(s + 1)^2 = 4

s + 1 = ±2

s = -3, 1

Calculating for t using equation 4:

when s = -3

t^2 = 2(-3)

t = sqrt(-6)

Since t is imaginary, therefore s=-3 is not a solution

when s = 1

t^2 = 2(1)

t = sqrt(2) = ±1.414

Therefore the maxima and minima points are at:

(1, -1.414) and (1, 1.414)

g(1, -1.414)=(-1.414)^2 e^(1) = 5.434

g(1, -1.414)=( 1.414)^2 e^(1) = 5.434
