The equation for the area of a circle is A = pi times r^2
The radius is half the diameter, making it 5.

A = pi times 5^2
Simplify to: A = pi times 25
A = 78.5

The sum of two nonnegative numbers is 50. What is the maximum value of the product of these two numbers ?
Umnica [9.8K]

Answer:

625

Step-by-step explanation:

Let two number be x and (50-x).

The product of numbers be x(50-x).

P = 50x-x²

For maximizing the product,

\dfrac{dP}{dx}=0\\\\\dfrac{d}{dx}(50x-x^2)=0\\\\50-2x=0\\\\50=2x\\\\x=25

So, the maximum product, P = 50(25)-(25)²

P = 625

Hence, the maximum value of the product of these two numbers is 625.

A trash can manufacturing company makes trash cans with the dimensions shown. They also make larger cans in which the radius and
fomenos
It is shown that by looking at the formula for the volume of a cylinder (we assume that the trash can is cylindrical):

V = pi*r^2*h

We can conclude that the volume of the trash can is directly proportional to its radius and height. To wrap up, the volume would increase as the radius of the trash can's base, and its height would be increased as well.

*****WILL GIVE BRAINLEST IF CORRECT******
PSYCHO15rus [73]

Conner's work is correct. To combine and make it simple, you Multiply:

(3^5+9)+(6^8+10) which will equal 3^14 6^18.

But Jane's work, instead of adding, Jane multiplies. So, Conner is correct.

Hope that helped!
