Answer:
See below
Step-by-step explanation:
Use the formulae directly
For a cone, with base radius = r and height = h, here are the related formula
(1)
(2)
(3)
Therefore directly plugging in the numbers in the above equations:
Note:
l = slant height in cm
SA = total surface area in sqcm
V = Volume in cubic cm
Figure(a)
r = 4, h = 8
Figure(b)
r = 7, h =15
Figure (c)
r = 5, l = 8
V= 50 degrees
This is because the line on which the angle 70 is at adds up to 180 and it we subtract 70 from the straight angle we have 110 degrees that means the other angle on the other side of the 70 is 110 so if we add 110 and 20 we get 130 and since all angles of a triangle add up to 180 we subtract 130 from 180 and get 50
Answer:
We can rearrange the interest formula
Answer:
74°
Step-by-step explanation:
From the attached figure, translation only affects the length of the sides of the triangle :
From the figure :
We are given ;
A = 80° ; C = 26° ; B =?
Sum of angles in a triangle :
A + B + C = 180°
80° + B + 26° = 180°
106° + B = 180°
B = 180 - 106
B = 74°
7,000 pounds is equal to 3.5 tons.
