It’s 67 is the square route
Answer:106.8 inches
Step-by-step explanation:
c = 2 x (3.14) x r
Which is 2(3.14)(17)
2(53.38)
106.76 = ~106.8inches
Answer:a) 84π b) 109.2π
Step-by-step explanation:
The formula to find this is v=πr^2h/3
r=d/2. so the radius (r) is 6 because you have to divide the diameter (12) by 2. and the height is 7. so, 6^2=36 and 36x7=252.
252/3=84
and because the question is asking for the EXACT value, you need to just put the pi symbol next to it. Final answer for a is 84π
B) you need to find 30% of 84, which is 25.2 and add it to 84, and you will get 109.2! Final answer is 109.2π.
3r+6-9r=24
-6r+6=24
-6r=24-6
-6r=18
r=-3
Answer is 14 I think pretty sure hope so yeah
