Need help ASAP. 1) Determine the volume of the figure that has a radius of 2 feet. Round your answer to the nearest tenth of a cubic foot.

We have two separate figures here, that have been combined to make one figure. We need to find the volumes of each figure separately, then add them together to find the total volume.

Formula for the volume of a circular cone: V = 1/3 x pi x r^2 x height

Formula for the volume of a cylinder: V = pi x r^2 x height

Solving for the volume of the circular cone:

V = 1/3 x pi x (2)^2 x 3

V = 1/3 x pi x 4 x 3

V = 1/3 x pi x 12

V = 4 x pi

V = 12.5663706144

Solving for the volume of the cylinder:

V = pi x (2)^2 x 10

V = pi x 4 x 10

V = pi x 40

V = 125.663706144

Adding the two volumes together and rounding:

125.663706144 + 12.5663706144 = 138.230076758

V = 138.2 ft^3

Hope this helps!! :)

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
