Answer:

3.5π cm²

Step-by-step explanation:

let P represent the perimeter of a circle with radius 7

P = 2×π×r

  = 2×π×7

  = 14π

the perimeter of a quarter-circle with radius 7 = P÷4

= 14π÷4

= 3.5π

Given that ABDC : EFGH, what is m G?<br> 27°<br> 90°<br> 117°<br> 120°
oksian1 [2.3K]
I think it would be 117

Because H is 63
So 90+90+63=243
360-243=117
I used 360 because angles in quadrilaterals add up to 360 degrees

Marking as brainliest!!!!
7nadin3 [17]

Answer:

The answer to your question is: Letter A

Step-by-step explanation:

Data

M (-6, 7)

E (4, 11)

r = 1 / 3

Formula

x = \frac{x1 + rx2}{1 + r}

y = \frac{y1 + ry2}{1 + r}

x = \frac{-6 + (1/3)(11)}{(4/3)} = \frac{-6 + (4/3)}{(4/3)}  = \frac{-18 + 4}{4} = \frac{-14}{4}  = \frac{-7}{2}

y = \frac{7 + (1/3)(11)}{4/3} = \frac{7 + (11/3)}{(4/3)} = \frac{21+ 11}{4}  = \frac{32}{4} = 8
