I need help in this question ​

Mathematics
1 answer:
Mamont248 [21]3 years ago
5 0

Answer:

17

Step-by-step explanation:

A straight line equals 180 degrees. The box on the left indicates a right angle which equals 90 degress. The 90 and 39 degress are given, and when added together that equals 129 degrees. If the total line is 180 degress, you would subtract the 129 degrees from it to get 51. This means that 3(x)= 51. You do 51/3 which equals 17, or x=17.

Volume of cone= 1/3πr^2h

8842.24 m^3= 1/3πr^2h

1/3*3.14*33*r^2= 8842.24m^3

r^2 = 8842.24*3/3.14*33

r^2= 26526.72/103.62

r^2 = 256

r= √256

r= 16m

Hope it helps. Please mark brainliest.

4. MAIL It cost Ramon $3.73 to mail a package to his grandmother. The post
Alex Ar [27]

Answer:

4 pounds

Step-by-step explanation:

First, I subtracted the cost of the first pound from the final product (3.73 - 2.38) and I got 1.35. I then divided the 1.35 by .45 (the 45 cents) to figure out how many more pounds the package was from the initial 1 pounds. 1.35/.45 is 3, plus the 1 pound from the beginning makes 4 pounds in total.
