Answer:

7241.25 mm squared

Step-by-step explanation:

The surface area of a cylinder is denoted by: A=2\pi r^2+2\pi rh, where r is the radius and h is the height.

Here, we know that the diameter is 39.2 mm, and since diameter is twice the radius, then r = d/2 = 39.2/2 = 19.6 mm. We also know that the height is 39.2 mm, so plug these values in:

A=2\pi r^2+2\pi rh

A=2\pi (19.6)^2+2\pi *19.6*39.2=7241.25 mm squared

The answer is about 7241.25 mm squared.

Answer:

surface area: 7241.25

Step-by-step explanation:

using this formula for surface area of cyclinder: 2πrh+2πr^2

diameter = 2r --> 39.2 = 2r

so r= 19.6

Solvex2<br> - 4x=21 <br> using the zero product property.
Ierofanga [76]

Answer:

The answer is (x + 3) (x - 7) = 0

Step-by-step explanation:

x² - 4x = 21

x² - 4x - 21 = 0

x² - 7x + 3x - 21 = 0

x(x - 7) + 3(x - 7) = 0

(x + 3) (x - 7) = 0

Thus, The answer is (x + 3) (x - 7) = 0

romanna [79]

Answer:

859

Step-by-step explanation:

The demand for Coke products varies inversely as the price of Cole products.

Mathematically:

D α 1/p

Where D = demand, p = price of coke product

D = k/p

Where k = constant of proportionality.

Let us find k.

k = D * p

When Demand, D, is 1250, price, p, is $2.75:

=> k = 1250 * 2.75

k = $3437.5

Now, when price, p, is $4, the demand will be:

D = 3437.5/4

D = 859.375 = 859 (rounding to whole number)

The demand for the product is 859 when the price is $4.

dexar [7]

Answer:

The System of linear equations are:

2a+3b = 82  

a+b=38

Step-by-step explanation:

Here, a represents the number of 2-points and b represent the number of 3-point basket.

As per the statement:

The basketball team scored 82 points from 2- points and 3-points baskets.

⇒ 2a+3b = 82  

It is also given that: They make 38 baskets altogether.

⇒a+b=38

therefore, the system of linear equations are:

2a+3b = 82  

a+b=38
