Answer:
C.
Step-by-step explanation:
The formula for surface area is
LA + 2B
LA indicated Lateral Area and can be found multiplying perimeter of base by the height.
7 + 7 + 14 + 14 = 42 * 7 = 294
Multiply the LA from above with the area of base times 2.
98 * 2 = 196
294 + 196 = 490, so the surface area of the rectangular prism is 490 units.
Answer:
Unit rate
Step-by-step explanation:
A unit rate describes how many units of the first type of quantity corresponds to one unit of the second type of quantity. Some common unit rates are miles (or kilometers) per hour, cost per item, earnings per week, etc.
No it is not a unit rate unless 11/3 is your numerator for a quantity of one. For example, "he finishes 11/3 of his homework every hour"
Answer:
The sum of the exterior angles of hexagon is 360° .
Step-by-step explanation:
Given as :
For a hexagon , let the sum of exterior angles = x
Now, for any polygon The sum of each exterior angle =
Where n is the number of sides of any polygon
If polygon is a hexagon ,
Then , for hexagon the number of sides = 6
∵ The measure of each exterior angle =
So, For hexagon , n = 6
The measure of each exterior angle =
I. e The measure of each exterior angle = 60°
So, The sum of the exterior angles of hexagon is 60° × 6 = 360°
Hence The sum of the exterior angles of hexagon is 360° . Answer
