Answer: 3900
ft^3
if you use the formula on how to find the volume of a cone
V=
r^2*h/3
you will insert 30 where the r is, 13 in where h is, after you just solve that and your answer would be 3900
ft^3
90-7 =83 degrees
height = 3 miles
divide 3 by the cos of 83 degrees
3/cos(83) = 24.6165
rounded to nearest mile = 25 miles
Answer:
120 cm^2.
Step-by-step explanation:
The area of one triangle = 1/2 * base * height
= 1/2 * 8 * 6
= 1/2 * 48
= 24 cm^2
So area of the pentagon = 5 * 24
= 120 cm^2.
