Answer: -3
Step-by-step explanation:
y2-y1/x2-x1
(1,0)
(0,3)
3-0/0-1 = -3/1
1) The perimeter is the sum of the lengths of the straight edge (the diameter of the semicircle) and the length of the arc of the semicircle.
The circumference of a 4 ft circle is
π*diameter = π*4 ft ≈ 12.566 ft
The semicircle will have a length that is half that, 6.283 ft. When this length is added to the diameter, the perimeter is found to be
Perimeter = 4 ft + 6.283 ft ≈ 10.3 ft.
2) The area of a circle is given by the formula
A = (π/4)d²
For a diameter of 15 inches, the area is
A = (π/4)(15 in)² = 56.25π in²
A ≈ 176.7146 in²
The area of the circle is about 176.71 in².
Well think about it. If you divide by something less than 1, your number gets bigger.

Same thing when it's negative, except now the answer is negative. So, if x gets really close to 0, it will be very big, or a big negative number. Remember, "getting close to 0" could mean from the negative side just as well from the positive.
Unable to see the paper clearly
There are infinitely prime numbers "p", but p+2 and p+4 are not primes.
Example: Suppose p = 7 (prime) if you add 2, it becomes 9 (Not a Prime).
Same thing if p = 11(prime), if yo add 4, it becomes 15 (Not a prime number)
