Answer:

The answer to your question is: I think is letter C

Step-by-step explanation:

Formula of circumference

                                           C = 2πr

where

C = circumference

r = radius

d = diameter

and

r = d/2

then

                                        C = 2 π d/2

                                        C = πd

                                        π = C/d     It is a division

Zina [86]

Answer:

2 dimes, 1 nickel and 3 quarters.

Step-by-step explanation:

The price of 2 postcards is $1. Any combination of coins that adds to $1 will work here. Remember, a penny is worth 0.01, a nickel is worth 0.05, a dime is worth 0.10, and a quarter is worth 0.25.

Adding 2 dimes, 1 nickel, and 3 quarters would be 2(0.10)+1(0.05)+3(0.25)=1.

Divide 32.85 by 15 help me work out the problem. please
Arlecino [84]
<em>The answer to 32.85÷15 is 2.19. First, you need to change 32.85 into a whole number. To do that, multiply by powers of ten. There are 2 powers of ten need to turn 32.85 to a whole number. Whatever you do to one side, you must do to the other. So, add 2 zeros to 15. The expression becomes 3,285÷1500. The answer is 2.19</em>
