How much greater is the area of a square with a side length of 9 inches than the area of a circle with a radius of 3 inches?
fredd [130]
The area of the square is 81 sq in, and the area of the circule is (3.14)(3 in)^2, or approx 3.14(9) sq in, or approx  28.27 sq in.

Subtract:  81 sq in - 28.27 sq in = approx. 52.73 sq in.

The difference is 52.73 sq in; the square is larger, the circle smaller.

Plz will mark as brainliest ​
Alenkasestr [34]

Answer:

30

Step-by-step explanation:

1/2 x (a+b) x h = area

1/2 x ( 40 + x ) x 50 =  1750

1/2 (40 + x )= 1750/50

20 + 1/2x = 35

1/2 x = 35 - 20

x = 15 x 2

= 30

I hope this is right :)

I need someone to answer this question the answer choices are below
olga nikolaevna [1]

Answer:

The answer is A, 18.84.

Step-by-step explanation:

The two points are 6 places apart, so that can be 6 units as radius. To find the circumference of a circle you do r x 3.14 (to abbreviate pi). 6 x 3.14 is 18.84 so A is your answer.
