7.1
Use the formula of a circle. The radius is 1.5 and squared that is 2.25. Multiply that by 3.14 for your answer.
13% = 13/100 = 0.13
3/25 = 0.12
0.13 > 0.12
So 13% is bigger than 3/25
3.5:1 into 28:x
so "x" = 28/3.5
"x" = 8
Answer:
<em>12 </em>
<em> + 28 </em>
<em> - 60 r³ + 28 r² </em>
Step-by-step explanation:
a(b ± c) = ab ± ac (distributive property)
2r²(6r³ + 14r² - 30r + 14) = <em>12 </em><em> + 28 </em><em> - 60 r³ + 28 r²</em>
