Answer:
85.6 cm^2
Step-by-step explanation:
The area of the central triangle bounded by each of the sides can be computed as ...
A = (1/2)r²sin(α) . . . . where α is the central angle, 360°/5 = 72°
There are 5 such triangles, so the area of the pentagon is ...
A = (5/2)(6 cm)²sin(72°) ≈ 85.595 cm²
The area of the regular pentagon of radius 6 cm is about 85.6 cm².
Step-by-step explanation:
here's your solution
=> volume of cylinder = πr^2h
=> radius of cylinder = 12 unit
=> height of cylinder = 17 unit
=> volume of cylinder = 2448 π units^3
Answer:
a^2+B^2=c^2
Step-by-step explanation:
4 1/2 + 8 3/4
4+8 = 12
1/2 + 3/4 = 2/4 + 3/4 = 5/4 = 1 1/4
12 + 1 1/4 = 13 1/4
Answer is C
P is equal to plus or minus 2 because it'll both be equal to 4
