Answer : The correct option is, (B) 1500 cubic yards.
Step-by-step explanation :
Formula used to calculate the volume of square pyramid is:
where,
V = volume of pyramid
a = base edge of pyramid
h = height of pyramid
Given:
Base edge of pyramid = 15 yards
Height of pyramid = 20 yards
Now putting all the given values in the above formula, we get:
Therefore, the volume of pyramid is 1500 cubic yards.
7056. 1008 x 7 = 7056. 7056 / 441 = 16
Answer:
363
Step-by-step explanation:
Formula for area of a circle
A = πr^2
Where r = radius
The circle has a given radius of 11
To find the area of the circle we simply substitute r in the formula with the value of the radius (11)
( Also note that the question says to use 3 for π )
A = πr^2
π = 3
r = 11
Substitute values in formula
A = (3)(11)^2
11^2 = 121
A = 121(3)
121(3) = 363
A = 363
Answer:
13.6 g/ml
Step-by-step explanation:
Density is found by mass divided by volume
The mass is 306.0 and the volume is 22.5 ml
density = 306.0/22.5 =13.6 g/ml
We have 3 sig figs which is correct
