A² + b² = c²
c² = 4² + 6.5²
c² = 58.25
c = 7.63
Perimeter = 4 + 6.5 + 7.63 = 18.13 units.
Perimeter after the increase in scale = 18.13 x 4 = 72.52 units.
Answer: 72.52 units
C=2πr
C=πd
A=πr^2
r=C/2π
r=1/2 d
<u>By the way all you do to solve r is: </u>
C=2πr
C/2π=2πr/2π
C/2π=r
r=C/2π
Hope this helps:)
Answer:
300
Step-by-step explanation:
V=4/3 * pi* r^3
If you sub in 100 for V, do some manipulation you get r cubed to equal 23.78.
Now put the value of 23.78 in for r cubed and V comes out to be 300
Answer. A. 78.5 kg
Explanation. First, we must convert the lbs into grams, we can do this my multiplying 454 by 173 and get 78,500. Then convert it to kg, there are 1,000 g in a kg do divide 78,500 by 1,000 to get 78.5 kg. Let me know if it’s correct so others can use it. Brainliest would be appreciated.
Good luck :)
The time of flight of a half projectile motion is given by V0 sin θ / g = 15(sin 45) / 9.8 = 1.08 seconds.
