Answer:
volume of a cone = 1/3*(πr²h)
Step-by-step explanation:
Answer:
perimeter = 28.13 cm
Step-by-step explanation:
Calculate the length of a line drawn from A to C.
sin 85 = b/8, b = 7.97
cos 85 = c/8, c = 0.697
AC² =7.97² + (6 + 0.697)² = 63.52 + 44.85 = 108.37
AC = 10.41
Now you have a right triangle ADC with a known hypotenuse and one leg.
Using the Pythagorean theorem:
DC² = 10.41² - 5²
DC² = 108.37 - 25 = 83.37
DC = 9.13 cm
perimeter = 5 + 6 + 8 + 9.13 = 28.13 cm
1/3 (0.333,,,) is 0.05666... away from 0.39 .
2/5 (0.4) is 0.01 away .
3.8 (0.375) is 0.015 away .
9/25 (0.36) is 0.3 away .
2/5 is the closest one.
Answer:
Red = 25/32768
Blue = 4/64
Step-by-step explanation:
Green Marbles = 1
Red Marbles = 5
Blue Marbles = 2
Probability of picking a red marble = 5/8 x 5/8 x 5/8 x 5/8 x 5/8 = 25/32768
Probability of picking a blue marble = 2/8 x 2/8 = 4/64
Think it’s A just because it’s actually decaying rather than being from decayed to up like B, C, and D( I don’t know how to explain it, sorry) I’m not sure however !
