In terms of pi: 164.5pi cm squared
Substituting pi for 3.14: 516.53 cm squared
Step-by-step explanation:
3.5^2 = 12.25pi
12.25*2 = 24.5pi
7pi*20 = 140pi
140 + 24.5 = 164.5pi
164.5*3.14 = 516.53
Answer:
old
Step-by-step explanation:
idk because I'm just to pit down this because we haven't learned this yet
multiply the number of ounces by the price per ounce
Blue jelly beans cost 0.28 per ounce and there are 4 ounces
4 * 0.28 = 1.12
red jelly beans cost 0.55 per ounce and there is 3 ounces
3 *0.55 = 1.65
now add the totals: 1.12 +1.65 = 2.77
this is more than the total they want of 2.20
so it is not reasonable.
