Answer:
(a) 113.04m²
(b) 37.68m
Step-by-step explanation:
(a)
Area = πr²
=π(6)²
=36π
=113.04m²
(b)
Circumference = 2πr
2π(6) = 12π
=37.68m
Answer:
29 and -26
Step-by-step explanation:
put the log into a graphing calculator its way easier just a tip
We know that
1 hour----------> 60 min
step 1
convert hours to minutes
<span>4:15---------> 4 hour +15 minutes------> 4*60+15-----> 255 minutes
step 2
</span><span>subtract 45 minutes
</span>255-45--------> 210 minutes
step 3
convert to hour
1 hour----------> 60 min
x-----------------> 210 min
X=210/60---------> X=3.5 hour
3.5 hour
that means
3 hour+0.5 hour
and 0.5 hour is-----------> 0.5*60----> 30 minutes
therefore
3.5 hour-------> 3 hour +30 minutes-------->3:30 pm
the answer is
3:30 pm
7/28
(Now we divide both sides by 7 since they can easily be divided by 7)
7÷7=1
28÷7=4
Since we can't divide 1/4 anymore, 7/28 as a simplified fraction is 1/4.
