It would be 20 inches
Since 400=x^2
The square root of 400 is 20
The number is (20 x 19 x 18 x 17) / (4 x 3 x 2). That's 4,845 . None of the choices is correct.
Answer:
for circle in circle: 75π
circle in square: 64-16π
note that answers are in exact form, since I don't know how the answer should be written (exact or decimal etc.)
Step-by-step explanation:
for circle in circle, we see that smaller circle (white circle) has radius 5 and big circle has radius 10. therefore we can find area of shaded area by doing
area of big - area of small
10²π - 5²π = 100π - 25π = 75π
circle in square, applying the same method, we can do square-circle
since the circle is inscribed in the square, the circle's diameter is 8, so its radius is 4
8²-4²π = 64-16π
Answer:
3.95 divided by 20 equals 0.1975
Answer:
-7.8k - 7.2
Step-by-step explanation:
Distribute 0.6 to the terms in the parentheses:
0.6(-13k - 12)
-7.8k - 7.2
So, the simplified expression is -7.8k - 7.2
