Hello!
We know that surface area of a cone = pi(r^2) + pi(rL) where L is the Slant height and R is the Radius and h is Height.
So, 30 is height, and half of 32 is the radius, then we just plug and chug,
An in Short, Your Answer would be 2512, Option "A"
Hope this Helps! :)
Answer:
Ratio of the perimeters =3:1
Step-by-step explanation:
We have given that : Ratio of the sides of two squares is 3:1
To find : Ratio of their perimeters
Solution : Let the length of the sides are 3:1 = 3x : x
Formula of perimeter of square = 4(side)
Using the formula ,
Perimeter of 1 square = 4×3x= 12x
Perimeter of 2 square = 4×x= 4x
Ratio of the perimeter of 1 square and 2 square = 12x : 4x
= 3 : 1
Answer:the coastline is 20000 miles.
The land boundaries are 12000 miles.
Step-by-step explanation:
The length of the entire border of the Unites States is approximately 32,000 miles.
5/8 of the entire length is the coastline. It means that the length of the coastline of the U.S would be
5/8 × 32000 = 20000 miles.
Therefore, the length of the boundaries of the US would be
32000 - 20000 = 12000 miles.
Answer:
Volume of a Rectangluar Prism: 288 ft
Volume of triangular prism: 12 ft
Volume of composite figure: 300 ft cubed (^3)
Step-by-step explanation:
Volume of a Rectangluar Prism: V=lwh
Volume of triangular prism: For this instance, we'll use V=1/2bh
The volume of the composite figure is the total of the volumes added
