A paper container in the shape of a right circular cone has a radius of 3 inches and a height of 8 inches. Determine and state t
Scrat [10]

Given:

Radius of the cone = 3 inches

Height of the cone = 8 inches

To find:

The volume of the cone, in terms of  π.​

Solution:

We know that, the volume of a cone is:

V=\dfrac{1}{3}\pi r^2h

Putting r=3,h=8, we get

V=\dfrac{1}{3}\pi (3)^2(8)

V=\dfrac{1}{3}\pi (9)(8)

V=\dfrac{72}{3}\pi

V=24\pi

Therefore, the volume of the cone is 24\pi.

the cost of renting a scooter is represented by 3j+5. Write and simplify an expression that represents the cost of renting 6 sco
wariber [46]

Simplified expression that represents the cost of renting 6 scooters is 18 j +30

<u>Step-by-step explanation:</u>

Given data:

The cost of renting of a scooter is represented by 3j +5

So, from that, we can say in general,

The cost of renting of n scooters is represented by  

                                 n \times(3 j+5)

But according to given, the value of n is 6. i.e. to find the cost for six number of scooters. We can calculate now as follows

So, the cost of renting of a scooter is represented by  

                                 6 \times(3 j+5)=18 j+30

What is a straight curve with no end pionts
Anni [7]

Answer:


Step-by-step explanation:

In mathematics, a curve (also called a curved line in older texts) is an object similar to a line but that need not be straight. Thus, a curve is a generalization of a line, in that its curvature need not be zero.

Angle measures and segment lengths. Algebra Find the value of each variable.
dolphi86 [110]

Answer:

x = 60°

Step-by-step explanation:

According to the Outside Angles Theorem, the angle formed by the two tangents in the diagram above is equal to half of the difference of the measures of two arcs  that are intercepted.

Therefore:

x = \frac{1}{2}(360 - 120) - 120)

x = \frac{1}{2}(240 - 120)

x = \frac{1}{2}(120)

x = 60°
