Answer:
=19
Step-by-step explanation:
=6÷3+17
=2+17
=19
The area of the regular octagon is calculated as half of the product of the perimeter and the apothem (ap), using the formula of the area of the regular polygon.
We have then:
A = ((p) * (ap)) / 2
Where,
p: perimeter
ap: apotema
Substituting values:
A = ((8 * 3.4) * (4.2)) / 2
A = 57.12 in ^ 2
Answer:
the area of the regular octagon is:
B. 57
19.2 is 24% of 80 when i did the work
Answer:
(b - c)(a - d)
Step-by-step explanation:
Given
a(b - c) + d(c - b) ← factor out - 1
= a(b - c) - d(b - c) ← factor out (b - c) from each term
= (b - c)(a - d)
Answer:
Step-by-step explanation:
area = 
so it's 
= 153.938... 
circumference is 2
r = 2*
*7 = 43.98229 cm
