Answer:
V = 2143.57
Step-by-step explanation:
To find the volume of a sphere you need to use this formula:
r = radius
Solve:
You need the radius from the diameter. Divide 16/2 which is
8.
V = 2143.57
Answer:
picture ?
Step-by-step explanation:
I believe you do it like this:
1/2 Q+5/2
divide 1/2 into each term
to divide multiply by the reciprocal
1/2 x2/1= 1
5/2 x 2/1=5
1/2(Q+5)
Answer:
the area of the sidewalk is 336 Sq. ft.
Step-by-step explanation:
8 + 25 = 33
8 + 9 = 17
17×33 = 561
25 × 9 =225
561-225=336
We know that the sum of all angles in any triangle is always 180 and we know that:
The smallest angle = x
Angle 2 = x + 35
Angle 3 = 3 * x
So:
180 = x + x + 35 + 3 * x
180 = x + x + 35 + 3x
180 = 2x + 35 + 3x
180 = 5x + 35 / - 35 (both sides)
145 = 5x / ÷ 5 (both sides)
x = 29
The smallest angle = 29
Angle 2 = 29 + 35 = 64
Angle 3 = 3 * 29 = 87
Check:
29 + 64 + 87 = 180, so it's correct :)
