2p + 2 = 24
2p = 22
p = 22/2
p = 11
Answer:
Step-by-step explanation:
22/7x4^2=50.28
3x3=9
50.28-9=41.28
Circumference = 2×3.14×r
3.14 is pie and r is the radius.
To find the radius you divide the diameter by 2.
19 ÷ 2 = 9.5
2×3.14×9.5 = 59.66
Multiply 59.66 by 6 because ther are 6 pennies.
59.66 × 6 = 357.96 mm.
Answer:
14.9 min
Step-by-step explanation:
r=rate
r25=5*7
r25=35
r=35/25
r=1.4
substitution
r160=t*15
t=time
r=1.4
1.4*160=t*15
224=t*15/15
224/15=t
14.9 min
