Answer:
6π cm
Step-by-step explanation:
Answer: 81 units²
Step-by-step explanation: To solve this problem, remember that the formula for the area of a square is 4s.
Therefore, since the perimeter of the given square is 36, we have 36 = 4s and dividing both sides by 4, 9 = s.
Now, remember that the formula for the area of a square is s² and since the length of a side of the given square is 9, we have (9)² or 81.
So the area of a square that has a perimeter of 36 is 81 units².
Answer:
The formula is simply this: C = πd. In this equation, "C" represents the circumference of the circle, and "d" represents its diameter. That is to say, you can find the circumference of a circle just by multiplying the diameter by pi.
If length is 42 inches, then width is 18 inches.
Step-by-step explanation:
We are given ratio of width to the length of a painting i.e 3 to 7. If the painting is 42 inches long, then how wide it is?
Solving:
So, If length is 42 inches, then width is 18 inches.
