11 is 4.5 feet and 12 is 11.71 miles
3x-5 < ( with line underneath the < sign) 21
Volume of the cone is ⅓πr²h where r= radius=1 in and h=5 in, so volume is 5π/3 cu in. Divide this into 5 equal parts, one part=π/3, so chocolate is 3 parts=π cu in=3.1 cu in = 3.1 cu in approx, answer C.
Answer:
5,5890
Step-by-step explanation:
First we multiply the first of it by second.
Then second by third and so on. Then use hero s formula on inverse trigonometry sin cos÷56
When the length of sides are given, you can use law of cosine to find the angles

11^=8^2+5^2-2*8*5cosA
-80cosA=32
cosA=-0.4
A is about 114 degree
use the same method to find out B and C, you will get 42 and 25
