Answer:

~ 30 cm^2

Step-by-step explanation:

area for rectangle (square is just rectangle with same length and width) = length × width

7cm × 7cm = 49cm^2

area for circle = pi×r^2 = pi×(d/2)^2

pi × ( 7cm / 2 )^2 = pi × (49cm^2 / 4) =

(22 / 7) × (49 / 4) cm^2 = (154 / 4) cm^2

((For area of half circle, just divide area of circle by 2))

Area_Square - Area_Half_Circle = Area_Remaining

49cm^2 - ((154 / 4)cm^2 ) / 2) = 49cm^2 - (77 / 4)cm^2

Area_Remaining = 29.75cm^2 --> ~30cm^2

This is my last question by the way
Leni [432]

Part A:

There are 25 blocks for the length, and the length of each is 5.5 inches. 5.5x25=137.5

There are 9 blocks for the height, and each is 2.75 inches. 2.75x9=24.75

Since we're trying to find how much longer the length is to the width, we find the difference. 137.5-24.75=112.75

So part A answer is <em><u>112.75 (or 112¾)</u></em>

Part B:

We know the length is 137.5 and the height is 24.75. To find how many times longer the length is, we need to divide to see how many 24.75 can go into 137.5.

137.5÷24.75=5.55

So the answer to part B is <u><em>5.55. Given the context, the answer would probably be 5, because that's how many entire height can fit.</em></u>

Can you guys distribute -9n-8-3n=6n-8 and figure out how many solutions it has plz
nydimaria [60]
First combine like terms (-9n-3n=-12n)
Then, subtract 6n on both sides (to get rid of the 6n) = -18n
Then, add 8 to both sides (does not matter) = 0
Finally divide (answer is 0)
