Given:
The diameter of the circle = 14 cm
To find:
The area of the circle.
Solution:
We have,
Diameter of the circle = 14 cm
We know that the radius of the circle is half of its diameter. So,
The area of a circle is:
Substituting 
in the above formula, we get
Therefore, the area of the circle is 154 square cm.
The answer is One solution because the two lines are crossing each other and has one point in common
What I suggest is to round the numbers. 4 rounds up to 5. 275 would round up to 280 or 300 whatever is easier. your expression would be 5*280 or 5*300.
I hope this helped :)
Answer:
it's 1/7^2
Step-by-step explanation:
When multiply bases with exponents, as long as they are the like bases, you add the exponents. 7^3 x 7^-5 = 7^-2.
When you have a negative exponent, you can get rid of it by moving it to a fraction. put a 1 over the base and exponent and drop the negative, so 1/7^2
