R=14.5
r=R/2
r=14.5/2
r=7.25
A= r^2π
A= 7.25^2π
A=165.04625

Find thy radius.

Thy radius is 7.25 (D / 2 = R)

Thy formula for area is A = (pi)r^2

Substitute and Solve

A = (pi)r^2
= (pi)(7.25)^2
= (pi)(52.5625)
= 165.04625

Therefore, the area is about 165.

PLEASE HELP WILL MARK BRAINLYST IF CORRECT Explain how to use the orders of operation to simplify the following expression. [– 4

Gekata [30.6K]

First do the the parenthesis: (6-3) = 3

Now you have [-4 + 3 * 8] -10

Next do multiplication: 3 *8 = 24

Now you have [-4 + 24]-10

Now do what is in brackets: -4 + 24 = 20

Now you have 20-10

Subtract 20-10 = 10

You are standing above the point (5,5)(5,5) on the surface z=15−(2x2+2y2)z=15−(2x2+2y2). (a) in which direction should you walk

Marianna [84]

Since the surface is the top part of a sphere centred on the origin, the directions of steepest descent are any vector originating from the origin (0,0).

At (5,5), the direction would be dictated by the line joining (5,5) and the origin (0,0), i.e. along <5,5> or equivalently along <1,1>.

You can also go through vector calculus to arrive at the same result.
