Answer:
244 cm³
Step-by-step explanation:
Step 1: Given data
Height of the prism with a pentagonal base (h): 8 cm
Area of the pentagonal base (A): 30.5 cm²
Step 2: Calculate the volume of the prism with a pentagonal base
We have a regular pentagonal prism, that is, the 5 sides of the base are equal and we know the area of the base and the height of the prism. We can calculate its volume using the following expression.
V = A × h
V = 30.5 cm² × 8 cm = 244 cm³
Answer:
Step-by-step explanation:
IF it is a SYMMETRIC kite
CB = CD
x + 4 = 2x - 1
x - x + 4 + 1 = 2x - x - 1 + 1
5 = x
AB = AD
x + 3 = 3x - y
5 + 3 = 3(5) - y
8 = 15 - y
y = 7
Yeah, mostly is has to be negative, but in some cases a is greater than 1 than we do some other operations.
