To find the area of a circle, you do π × diameter (in this case 10). They have told you to use 3.142 as π, so you do 3.142 × 10 = 31.42. Because it's a semi-circle, you need to halve 31.42 to get 16.21, which is the answer

A = \pi x r²
A = 3.142 x 5²
A = 9818.75

4) How many km in<br> 58,795cm?<br><br><br> Please help thanks!!
Leto [7]

Step-by-step explanation:

1 km is equal to 100,000 cm.

58,795 is close to 50,000, which is half of 100,000. So our estimate would be 1/2 km to 50,000 cm.

Convert 58,795 to a decimal.

0.58795

The decimal cannot be simplified so there is

0.58795 km in 58,795 cm

Hope it helps!

A picnic bench is 2 meters long. how many decimeters is the bench
ra1l [238]
Ok, here's a trick: If you're converting a smaller unit to a bigger unit in metric system, you divide by 10. When you are trying to convert a bigger unit to a smaller unit, multiply by 10. Decimeters are 1/10 of a meter, so you are going to multiply 2 by 10 because you are converting a bigger unit to a smaller unit, in which you get 20.

So your answer is 20 decimeters.

➷ First, we need to figure out the total number of candies:

3 + 4 + 3 + 2 = 12

Keep this number in mind as it will be the denominator

There are 3 yellow candies so the probability would be:

\frac{3}{12} or \frac{1}{4}

Two buses leave a station at the same time and travel in opposite directions. One bus travels 15 mph faster than the other. If t
Artemon [7]

Answer:

46 mph and 61 mph

Step-by-step explanation:

Distance=speed*time

Let speed of one bus be x and another x+15

After 3 hours

First bus would have traveled 3x while second bus 3(x+15)=3x+45

Total distance= 3x+3x+45=6x+45

6x+45=321

6x=321-45=276

x=276/6=46 mph

x+15=46+15=61 mph
