Answer:

You first work out the radius, as below:

Area = pi x radius^2

=> radius = sqrt(Area/pi)

Then, you find out circumference C.

=> C = 2 x pi x radius

Hope this helps!

What is 55 1/5 - 32 3/4
garik1379 [7]

Answer:

449/20 or 22 9/20

Step-by-step explanation:

Change them to mixed numbers.

55 x 5 = 275 + 1 = 276

32 x 4 = 128 + 3 = 131

Then, convert them to a common denominator.

276 x 4 = 1104

131 x 5 = 655

1104 - 655 = 449

449/20

zalisa [80]

Answer:

4

Step-by-step explanation:

The first term is the value of the term when n=1. It is 3. The common ratio is is the value being raised to the power of (n-1). It is 1/4. Put these numbers into the formula and do the arithmetic

S = 3/(1 -1/4) = 3/(3/4) = 3·4/3 = 4

The sum is 4.

A bicyclist races on a bicyclist with 13-inch-radius wheels. When she is traveling at a speed of 37 ft/sec, how many revolutions
drek231 [11]
Radius of a wheel = 13 inch
= 1.08333 ft
circumference of a wheel = 2×pi×r^2
= 2 × (22/7) × 1.08333^2 ft
= 2 × (22/7) × 1.1736 ft
= (44/7)×1.1736 ft
= 51.6384/7 ft
= 7.3769142857 ft
distance covered in one minute = 37 × 60 ft/min
= 2220 ft/min
now, revolution per minute = 2220 / 7.3769142857
= 300.93884
therefore her wheels are making 300.93884 revolutions per minute
