Hey there! :)
Answer:
r ≈ 4.38 cm.
Step-by-step explanation:
Find the radius by working backwards using the equation A = πr²:
Given:
A = 60.24 cm²
π = 3.14
Plug these into the equation:
60.24 = 3.14r²
Divide both sides by 3.14:
19.185 = r²
Take the square root of both sides:
r ≈ 4.38 cm.
Answer:
They are equal and act in opposite directions.
Step-by-step explanation:
Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object.
Answer:
80 cm as a fraction of 4 m is
Step-by-step explanation:
To write the fraction of two different quantities you must put them in the same units
<u><em>Example:</em></u> To write 5 grams as a fraction of 1 kilogram
- Change the 1 kilogram to grams by multiplying it by 1000
- The fraction will be
- Reduce it to its simplest form by divide up and down by 5 to be
<em>Let us use the same way to solve the question</em>
∵ 1 meter = 100 centimeters
∴ 4 meters = 4 × 100 = 400 centimeters
→ Now put 80 centimeters as a numerator and 400 centimeters as
a denominator
∵ The fraction is
→ Divide up and down by 80 to simplify it
∴ The fraction =
∵ 80 ÷ 80 = 1
∵ 400 ÷ 80 = 5
∴ The fraction in its simplest form =
∴ 80 cm as a fraction of 4 m is
