Complete the statement by typing the letter of the angle.
m_= 54°

m∠B=54°

Step-by-step explanation:

use the fact that the sum of angles in a triangle is 180°

2x+7+4x-10+7x-25 =180

combine like terms

13x -28 =180

13x = 180+28

x= 208/13= 16

∠B = 4x-10 = 4*16 -10 = 64-10= 54°

y=mx+b is the final answer!   : )

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
