Answer:
V≈17974.16
Step-by-step explanation:
Using the formulas
V=4
3πr3
d=2r
Solving for V
V=1/
6πd^3=1/
6·π·32.53≈17974.16422
Answer:
Step-by-step explanation:
d
Answer:
20 square units
Step-by-step explanation:
The area of a parallelogram is the product of its base length and the height measured perpendicular to the base.
Here, the base is 5 units and the height is 4 units. These can be seen by counting the grid squares.
A = bh
A = (5 units)(4 units) = 20 units²
The area is 20 square units.
Answer:
Step-by-step explanation:
a true
b false
Answer:
It's b: a = 10√3, b = 5√3 , c = 15 and d = 5.
Step-by-step explanation:
We have two 30-60-90 triangles here so the sides are in the ratio 2:1:√3.
Consider the small triangle whose hypotenuse is 10:
1/2 = d/10
d = 10/2 = 5.
b / 10 = √3 /2
b = 10√3/2 = 5√3.
Now, the larger triangle to the left:
2 / 1 = a / 5√3
a = 10√3.
2 / √3 = 10√3 / c
c = 30/2 = 15.
