If the diameter of a circle with a circumference of 19.5 inches is reduced by three, what would be the circumference of the new

Elanso [62]

It is given that the circumference of the circle is 19.5 inches. Let the diameter is d inches .

And the formula of circumference is

$C= \pi d$

Substituting the value of C, we will get

$19.5= \pi d
\\
d = \frac{19.5}{ \pi}$

When the diameter increased by 3, then the circumference is

$C = \pi ( \frac{19.5}{ \pi} +3})=Approx 29 inches$

And the circumference , when diameter is increased by 3 is 29 inches .

You practice your basketball shots every day. On Friday you made 20 shots. On Saturday you made 16 shots. What is the percent de

STatiana [176]

So,

All you have to do to find the percent decrease is to subtract your score on Saturday from your score on Friday and divide the result by your score on Friday. If you let "f" represent your score on Friday and let "s" represent your score on Saturday, you can re-write this mathematically:

$\frac{f - s}{f} = percent\ decrease$

Substitute.
$\frac{20 - 16}{20} = percent\ decrease$
$\frac{4}{20} \ or\ \frac{1}{5}\ or\ twenty\ percent = percent\ decrease$

The percent decrease in shots you made was 20%. That would be option C.

Fraction -> Decimal

4/5 = 0.8

1/8 = 0.125

Decimal -> Percent

0.22 * 100% = 22%

0.47 * 100% = 47%

Percent -> Fraction

34% / 100 = 0.34 = 17/50

25% / 100 = 0.25 = 1/4

Fraction -> Percent

1/3 = 0.33... * 100% = 33.3%

2/5 = 0.4 * 100% = 40%

Decimal -> Fraction

0.65 = 65/100 = 13/20

0.4 = 4/10 = 2/5

Percent -> Decimal

81% / 100 = 0.81

4% / 100 = 0.04

Best of Luck!
