Answer:
A= pi r(r+h2+r2)
Step-by-step explanation:
Multiply the radius by pi, then set that aside for a bit.
Square the height and the radius as well, then add those together. This is how it would look:
3.14 x 4 = 12.56
7 x 7 = 49 ; 4 x 4 = 16 ; 16 + 49 + 4 = 69 ; 69 x 12.56
I think this is the answer. Can't say I'm 100% sure, though.
It will take about 2 hours and 15 minuets
Hope this helped!
Answer:
32
Step-by-step explanation:
Calculation for how much birdseed does she have left over
First step
(3*8*6*12) - 4-2*30
Second step
=[24+6*(10+2)] - 4-60
Third step
Let remove the bracket of (10+2)
=[24+6*10+6*2] - 4-60
Fourth step
=(24+60+12) - 4-60
Fifth step
=(84+12)-4-60
Sixth step
=96-4-60
Seventh step
=92-60
=32
Therefore the amount of birdseed that she have left over will be 32
Per year 7% for $2000 bond. It will be $140 per year.
Then per 6 months, it will be $70.
so, answer is B.
