The radius of a semicircle is extended by 6 inches.how does the measure of the semicircles arc length change?
vivado [14]
Let x be the original radius.  Given that a semicircle will have an arc length of half of a circumference and C=2pr, the arc length will be just pr.

Now the difference of arc is then going to be:

p(6+x)-px

p(6+x-x)

6p inches

So the arc will be 6p inches longer.  Or if you wish to approximate...

≈18.85 inches

The accompanying data represent the actual amount (in mL) poured into a short, wide glass for individuals asked to pour 44.3 mL
kherson [118]

Answer:

Kindly check explanation

Step-by-step explanation:

Given the data below :

x : 89.3 68.6 32.7 37.3 39.7 46.7 66.1 79.4 66.4 52.1 47.3 64.4 53.7 63.4 46.2 63.0 92.1 57.6

Mean(m) = ΣX / n

ΣX = 1066 ; n = number of observations = 18

Mean(m) = 1066 / 18

Mean = 59.22

Standard deviation (σ) :

Using the online standard deviation calculator :

σ = √(Σ(x - m)²/n-1)

σ = √264.198395

σ = 16.72

The mean amount poured into a glass for the 18 samples is 59.22 while the variation in the data samples from the mean value is 16.72.

typical amount poured into a short, wide glass is 19.7 mL. A typical deviation from the mean amount poured is_____mL.

(59.22 - 19.7) mL = 39.52mL

Mean amount poured into a tall slender glass = 51.283

Mean (short wide glass) = 59.22mL

Mean (tall slender glass) = 51.283mL

Short wide glass > tall slender glass

Cost price=CP=</span><span>8500*11.45=97325
gain=sp-cp=</span><span>70805</span>

gain%=gain*100/cp=7080500/97325=72.75%

so, False
