Answer:
i got -8 but the closest is -7 so u can tried that
Step-by-step explanation:
C=2*3.14*7.6
C=47.728
Round.
47.7
Therefore, the circumference is 47.7 m.
P-0.40p = 0.60p
C. Decrease by 40% is the same as multiply by 60%.
Assume that p = 10
10 - 0.40(10) = 0.60(10)
10 - 4 = 6
6 = 6
Based on the above assumption. 40% of 10 is 4 ; and 60% of 10 is 6. So, 10 less 4(40% of 10) is equal to 6 (60% of 10).
Percentage is used because 0.40 and 0.60 will be multiplied with 100% to get the equivalent percentage 0.40 x 100% = 40% ; 0.60 x 100% = 60%
3*3*3=9 perhaps?? And then it would be in Surface Area??
