Answer:
V = 32/3 pi
Step-by-step explanation:
The volume of a sphere is given by
V= 4/3 pi r^3
We know the radius is 2
V = 4/3 pi (2)^3
V = 4/3 pi (8)
V = 32/3 pi
Answer:
1, 4, or 7
Step-by-step explanation:
For 425,9__0 to be divisible by three, the sum of the digits must be a multiple of three.
Using this knowledge, the numbers 1, 4, and 7 are all answers to this problem.
425, 910: 4 + 2 + 5 + 9 + 1 + 0 = 21
21 is divisible by 3.
Repeat this for 4 and 7.
Hope this helped!
Answer:
x=3cm
Step-by-step explanation:
We have three figures.A triangle(8 by X+3).In it we have another triangle(4 by x)and a trapesium
thus that means the area of the trapesium+area of small triangle=area of big triangle.
1)Area=1/2lengthxwidth. =1/2×8×(x+3)
=4(x+3)
=4x+12cm³
2)Area=1/2lengthxwidth. =1/2×4×x
=2x
3)area=1/2(a+b)h
=1/2(x+3+x)×4
=1/2×4(2x+3). (area of trapesium)
=2(2x+3)
=4x+6cm³
thus:
2x+4x+6=4x+12 put like terms together
2x+4x-4x=12-6
2x=6 divide both sides by 2
x=3cm
Answer: The answer is C, 102 degrees
Step-by-step explanation:
A triangle must add up to 180 degrees, you add 28 and 50, which gives you 78. 180 minus 78 is 102. So the answer is 102 degrees.
