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:
c) r = 4x + 2y
Step-by-step explanation:
∑y
-3 + 5 =2
∑x
1 + 3 = 4
r = 4x + 2y
Answer:
Step-by-step explanation:
Haiiiii
The third one. The two angles don't necessarily have to be equal
2 3/4a=9 1/4
2.75a= 9.25
cross off 2.75 and a will remain
divide 9.26 and 2.75
so a=3.36363636
a=<span>3.36363636
but you can round it to a=3.4ish i guess</span>
