Answer:

B)113.04 cm^2

Step-by-step explanation:

circumference is 37.68

C=2πr

now the Area is

A=πr^2

we need to know the radius

so 37.68=2(3.14)r

divide both sides by 2(3.14)

get

r=6

now solve for area

A=(3.14)(6)^2

=113.04

Suppose three riders rode a total of 182 miles. If they used a total of 13 horses, and rode each horse the same number of miles,
umka21 [38]

Answer:

They rode 14 miles before replacing each horse

Step-by-step explanation:

We will be working under the assumption that all three riders sat on one horse at a time and rode it while the other horses rested.

From the problem, we can understand that the horses were each ridden for the same distance. This means that to get the total distance a horse rode before it was changed, we can divide the total distance by the number of horses that were used for the journey.

Distance each horse rode = 182/ 13 = 14 miles.

Therefore, each horse was ridden for 14 miles before it was changed.

8+(14+6) FIND EASIER EXPLAIN WHY
alexandr1967 [171]

Hi there and welcome to Brainly!


The answer to 8+(14+6) = 28. The reason for this is you add what is in parenthesis first then you add the number outside of the parenthesis. This follows the PEMDAS rule which is called the order of operations. PEMDAS is an acronym which stands for Parenthesis, Exponents, Multiplication/Division, and Addition/Subtraction, this is the order you should follow when solving any problem.


If you have anymore questions please feel free to ask them.
