WHEN I FIND OUT ILL HELP YOU
Step-by-step explanation:
The volume of a pyramid or cone is:
V = ⅓ Ah
where A is the area of the base and h is the height.
The pyramid has a square base, so:
A = s²
A = (7 cm)²
A = 49 cm²
The height is 14 cm, so the volume is:
V = ⅓ (49 cm²) (14 cm)
V = 686/3 cm³
V ≈ 228.67 cm³
Answer:
y =52
Step-by-step explanation:
We know that the angles 4x and 5x make a straight line
4x+5x = 180
9x = 180
Divide by 9
9x/9 = 180/9
x = 20
The three angles of a triangle make 180
y + 48 +4x = 180
y + 48+4(20) =180
y + 48 +80 = 180
Combine like terms
y +128 = 180
Subtract 128 from each side
y + 128-128 = 180-128
y =52
