Answer:
12 cm
Step-by-step explanation:
The distance to the chord is the median of an isosceles right triangle with hypotenuse 20 and leg 16. This 5:4 ratio suggests the other leg of that right triangle would make the ratios 3 : 4 : 5, so is 12.
The chords are 12 cm from the center.
_____
You can, of course, use the Pythagorean theorem. If c is half the chord length and d is the distance to the chord, you have ...
c² + d² = r²
16² + d² = 20²
d² = 400 -256 = 144
d = √144 = 12 . . . . . cm
Answer:
(2,-4)
Step-by-step explanation:
Just plug in the numbers
6(2)- (-4)/2=14
12- -2=14
14=14
Answer:
B
Step-by-step explanation:
57 over three means

It is the same as asking how many times does 3 go into 57, or how many miles is their per one gallon.
57 divided by 3 equals 19, so B would be the correct answer.
Answer:


Step-by-step explanation:
1) v= 1/3 ab ×h
v= 1/3 (10)(10)×√13²-5²
v= 400 ft²
-------------------
2) v= πr² h/3
v= 1/3 × π×(6)²×29
v= 1/3×π×12×29
v= 348π
v= 1093.27
≈1093.3
