Answer:
6. 8 mi³
7. 72 cm³
Step-by-step explanation:
6. Volume of triangular pyramid = ⅓*A*H
Where,
A = area of triangular base = ½*b*h = ½*3*4 = 6 mi
H = height of pyramid 4 mi
Volume = ⅓*6*4 = 8 mi³
7. Volume of triangular prism = ½*bhl
Where,
b = 3 cm
h = 6 cm
l = 8 cm
Volume = ½*3*6*8 = 72 cm³
Answer:
96
Step-by-step explanation:
40=4x+8
32=4x
x=8
other side x+4 is 12
area is 12×8
96
Answer:
Step-by-step explanation:
For this exercise you need to use the formula for calculate the measure of the angle formed by two tangents intersecting outside of a circle. This is:
According to the information given in the exercise, you know that:
Since there are 360 degrees in a circle, you can determine that:
Therefore, knowing these values, you can substitute them into the formula given above and the evaluate, in order to find the measure of the angle EYL. This is:
If you get 4.4 interest in 1 year and 6 months is half of year, take half of 4.4 and multiply if by 550. Getting 1,210.
