Mathematics
1 answer:
Rzqust [24]3 years ago
3 0

Answer:

Circumference of Circle A is about 16 units larger than the Circumference of Circle B

Step-by-step explanation:

Formula for Circumference of a circle = πd

Where, d = diameter of circle

Thus:

Circle A diameter = 13

Circle B diameter = 8

Therefore:

Circumference of Circle A = π*13 = 40.8407045 ≈ 41 unit (nearest whole number)

Circumference of Circle B = π*8 = 25.1327412 ≈ 25 unit (nearest whole number)

✔️Difference between circumference of Circle A and Circle B = 41 - 25 = 16

Therefore the Circumference of Circle A is about 16 units larger than the Circumference of Circle B

A driver who drives at a speed of r mph for t hr will travel a distance d mi given by dequalsrt mi. How far will a driver travel
liubo4ka [24]

Answer:

At a speed of 57 mph for 8 hr a driver will travel 456 mi

Step-by-step explanation:

Here we have a summary of the letters for each variable:

Speed ---> r          (in units of mph)

Time ---> t            (in units of hr)

Distance ---> d     (in units of mi)

These three variables are related by the next formula:

d = rt

In the data they give to you: 57 mph and 8 hr, they are telling you the r and the t, respectively:

r = 57 mph

t = 8 hr

The only thing you have to do is replace the values:

d = rt    ---->     d = 57 mph x 8 hr

                        d = 456 mi

3. Four chicken nuggets have 180 calories. How many calories are in 9 chicken
Lemur [1.5K]

Hey there! :)

Answer:

405 calories.

Step-by-step explanation:

To solve, we can create a proportion.

We are given that 4 nuggets is equivalent to 180 calories, therefore:

\frac{180cal}{4}= \frac{xcal}{9}

Cross multiply:

9 · 180 = 4 · x

1620 = 4x

Divide both sides by 4:

x = 405 calories.
