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:
8
Step-by-step explanation:
128-16=112
112÷15(boys+girls)=7.4666666
7.4666666 rounds to 8
Answer:
to find the distance between two points, in order to find the length of the triangle we need first to find the instance between the two points
distance between (2,9) and (2,4) .....a =5
distance between (2,4) and (6,4) .....b = 4
when we find the length of the side of the triangle , then we can apply the Pythagorean theorem to find hyp. c
a²+b²=c²
Box 1 : 2
Box 2: 3
Box 3: 6
You need to order the data, so
11, 12, 13, 14, 14, 15, 17, 17, 18, 18, 18, 20
Then find the middle of the data. Because there are 12 data points, the median will lie between the two 6th placed numbers
The two numbers are 15 and 17, so work out the mean of them. (15+17)/2 = 16
So the answer is B. 16
