Temp. at 6 pm. was 72...
that temp. was 8 less then at 4 pm....so at 4 pm, it was 72 + 8 = 80
the temp. at 10 am was 5 greater then at 4 pm.....so at 10 am, it was 80 + 5 = 85 F <===
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.
-54 / -2 = 27
So yeah, 27 would be your answer.
Hope this helped :)
Answer:
11.39
Step-by-step explanation:
-3.86+6.82=2.96
abs(2.96)=2.96
----------------------
4.02-12.45=-8.43
abs(-8.43)=8.43
-----------------------
1(2.96)+8.43=2.96+8.43=11.39
