Volume = area of base *height
20 = pir^2 *h
20 = 3,14*4*h
h = 20/12,56 = 1,59 rounded 1,6
- using the triangle formed by radius,the height of cup and the slant height of cup so we can writing that
tan ß = h/r so tan ß = 1,6/2 = 0,8
tan ß = 0,8 so ß = arctan 0,8 = 38,6 degrees so 39 degrees
hope helped
Answer:
25, 90, and 65
Step-by-step explanation:
so the measures have to add up to 180, because it's a triangle, and we know 25 and 90 ( the box corner thing means that angle is 90) so we add 25 and 90 to get 115, and then we subtract 115 from 180, which gets us 65.
h=4 because 4+6=10 and 10/5=2
5.77
By 0.07
Because if you subtract 0.07 from 5.77, you get 5.7, so it must be smaller.
5,998.7714 ft
Step-by-step explanation:
Well find x in the illustration;
First To find the opposite side of the right-angled triangle we'll using tangent of the given angle
Tangent Ф = Length of the opposite side / Length of the adjacent side
Tan 43 = h / 6390
h = Tan (43) * 6390
h = 5,958.7714 ft
Then we'll add the height of the beacon which is 40 ft above ground;
x = 5,958.7714 ft + 40 ft
x = 5,998.7714 ft
