Find the average download rate.
(38.4 - 9.6) / (2-8) = -4.8 mb/min
that means in the first 2 min she had downloaded 2(4.8) = 9.6 mb
38.4 mb left + 9.6 mb already downloaded = 48 mb total
Answer:
141.4 sq cm
Step-by-step explanation:
to find the area of the outer circle with a smaller circle inscribed within, you find the area of each and subtract the smaller area from the larger
the radius of the smaller circle is 2
we have to find the radius of the larger circle so we use what we know about its circumference:
C = 2πr
43.96 = 2πr
21.98 = πr
21.98 / π = r
r ≈ 7 cm
now use r = 7 to find area of larger circle:
A = πr²
A = π49
Area of smaller circle: 4π
Area of larger circle without including inner section is 49π - 4π = 45π
45π ≈ 141.4 sq cm
Answer:
V = 1436.76
Step-by-step explanation:
<u>Formula:</u>
V = 4/3πr³
<u>Given:</u>
r = 7
<u>Work:</u>
V = 4/3πr³
V = 4/3π(7³)
V = 4/3π(343)
V = 1436.76
A. 65 is the answer for you!
Answer:
12
Step-by-step explanation:
Well, to make things easier, we can first note that 24/4 is equal to 6. This helps because integers are easier to work with compared to fractions. Next, multiplying 2 by 6, we get 12.
