One link in a chain was made from a cylinder that has a radius of 2 cm and a height of 20 cm. How much plastic coating would be

bezimeni [28]

Answer: 251.2cm^2

Step-by-step explanation:

Given radius of the cylinder 'r' = 2 cm

Given Height of the cylinder 'h' = 20 cm

Area of the curved surface = 2 π r h

The plastic coating would be needed to coat the surface of the chain link

A = 2 π r h

A = 2 × 3.14 ×2×20

A = 251.2 cm²

Conclusion:-

The plastic coating would be needed to coat the surface of the chain link = 251.2 cm²

F(x)=3x+4. Determine the value of F (X) when X equals -1

hammer [34]

ANSWER

The value of this function at x=-1 is 1

EXPLANATION

The given function is

$f(x) = 3x + 4$

We want to find the value of this function at x=-1.

We substitute x=-1 into the function to obtain:

$f( - 1) = 3( - 1)+ 4$

We multiply out to obtain:

$f( - 1) = - 3+ 4$

$f( - 1) = 1$

Therefore the value of this function at x=-1 is 1.
