Answer:
Given - Diameter of circle = 14 in
To find - Area of circle
Solution -
Diameter= 2 × Radius
14 = 2 × R
14/2 = R
7 = R
Area of circle= π r^²
22/7 × 7 × 7
22 × 7

Yes, because a rational number is any number that can be expressed as a fraction a/b where a/b are both integers, but cannot be zero.
The speed of the motorcycle will be 30 meters per second.
<h3>What is speed?</h3>
The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.
We know that the speed formula
Speed = Distance/Time
A motorcycle zoomed along the freeway, traveling 10 meters in 1/3 of a second.
Then the speed of the motorcycle will be
Speed = 10 / (1/3)
Speed = 10 x 3
Speed = 30 meters per second
The speed of the motorcycle will be 30 meters per second.

Answer:
(42-24n)
Step-by-step explanation:
(7-4n)×6
take the 6 and multiply it to the integers in the paraenthesis.
so you take the ouside number which is 6 and multiply it with the first number which is 7 in the paraenthesis.
6×7=42
(42-4n)
then take the next number 4n and multiply by 6
4n × 6 = 24n
finally put it all together
(42-24n)
sorry if that didnt help
