What is the difference between the areas of a circular table with diameter 6ft and a circular table with diameter 8 ft ? Round y
miskamm [114]

Answer:

22 ft^2

Step-by-step explanation:

The area of a table with diameter 6 ft

A = pi r^2 = pi (6/2) ^2 = pi 3^2 = 9pi

The area of a table with diameter 8 ft

A = pi r^2 = pi (8/2) ^2 = pi 4^2 = 16pi

Subtract 16pi-9pi = 7pi

Using 3.14 for pi

7 * 3.14

21.98 ft^2

To the nearest square foot

22 ft^2

What is the value of y in the solution to the following system of equations? 2x y = −4 5x 3y = −6
luda_lava [24]
2x + y = -4 . . . (1)
5x + 3y = -6 . . (2)

From (1), y = 4 - 2x . . . (3)
Putting (3) into (2), gives
5x + 3(4 - 2x) = -6
5x + 12 - 6x = -6
-x = -6 - 12 = -18
x = 18

From (3), y = 4 - 2(18) = 4 - 36 = -32

If m<10= 77, m<7=47 and m<16=139, find the measure of the missing angle m<4=?
worty [1.4K]

So, if the angle 16 is equal to 139; by knowing that angles opposite the vertex have equal measure, since they have equal amplitude, we can conclude that angle m4 is equal to:

\angle4=139
