6)
P of <span>Regular heptagon = 7a = 7 x 12 = 84
Area </span>of Regular heptagon = 1/2 P a
Area of Regular heptagon = 1/2 (84)(8)
Area of Regular heptagon = = 336
answer
B. 336
7)
P of Regular nonagon= 9a = 9 x 9 = 81
Area of Regular heptagon = 1/2 P a
Area of Regular heptagon = 1/2 (81)(16)
Area of Regular heptagon = = 648
answer
D. 648
Answer:
0 and 40
Step-by-step explanation:
First expression: 4*5 - (22 - 2). We must do work inside parentheses before any other work. This, we have 4*5 - (20), which simplifies to 20 - 20 = 0
Second expression: (18 - 3) + (32 - 7 becomes (15) + 25, or 40.
Answer:
its +
Step-by-step explanation:
Answer:
Step-by-step explanation:
The largest cross-section of a sphere is the center.
So, we have:
Where
Solving (a): The radius
implies that
Express as fraction
Divide by
Make r the subject
Solving (b): Area of the largest cross-section.
Solving (b): Volume of the sphere
A pie chart would be the best since you are breaking apart the amount of choices from the whole. (Corn, Carrots, Green beans sweet potatoes). If not a pie chart I suggest a bar graph.
