The diameter of a Canadian penny is 19 millimeters. The diameter of a Canadian nickel is 21 millimeters. How much greater is the area of a Canadian nickel than
the area of a Canadian penny? Show your work.

The Canadian nickel is 62.8 mm^2 greater in area as compared to Canadian penny.

Step-by-step explanation:

Diameter of Canadian penny = 19 mm

Diameter of Canadian nickel = 21 mm

We need to find How much greater is the area of a Canadian nickel than

the area of a Canadian penny?

First we need to find area of both nickel and penny

They are in circular form, so formula used is:

Finding area of Canadian penny

We know that radius = diameter/2

So, radius = 19/2

radius = 9.5

Area will be:

So, area of Canadian penny = 283.385 mm²

Finding area of Canadian nickel

We know that radius = diameter/2

So, radius = 21/2

radius = 10.5

Area will be:

So, area of Canadian nickel = 346.185 mm²

Difference in area can be calculated as: 346.185-283.385 = 62.8

The Canadian nickel is 62.8 mm^2 greater in area as compared to Canadian penny.

i think the answer is fried chicken ; >

step-by-step explanation:

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
