4) f (x)=x^3+2
5) f (n)= 5 square root of (-n+1/2)
Answer:
Volume of the portion = 1.6 cubic inches
Step-by-step explanation:
Since, wooden dowel is in the shape of a cylinder,
Formula to be used to find the volume of the part Anna has cut from the dowel will be,
Volume = πr²h
Where r = radius of the cylinder or part of the wooden dowel
h = length of the portion
By substituting the values in the formula,
Volume = π(0.5)²(2)
= 0.5π
= 1.57 in³ ≈ 1.6 cubic inch
Therefore, volume of the portion will be 1.6 in³.
11.5 cm
B
D
12.5 cm
13.5 cm
Answer:
100cm
Step-by-step explanation:
From the given diagram;
Perimeter of the polygon = AB + BC+ CD + DA
Perimeter of the polygon = 11.5 + 12.5 + 12.5 + 13.5 + 13.5 + 12.5 + 12.5 + 11.5
Perimeter of the polygon = 24 + 26 + 26 + 24
Perimeter of the polygon = 50 + 50
Perimeter of the polygon = 100cm
Hence the Perimeter of the polygon is 100cm
Answer:
100 cm
