The length of the diameter is 2.86 cm rounded to 2 DP

Step-by-step explanation:

The formula of the circumference of a circle is

  • C = 2πr, where r is the radius of the circle
  • C = πd, where d is the diameter of the circle

∵ The circumference of a circle is 8.97 cm

- We need to find the diameter of the circle, then we will use

   the 2nd formula of circumference above

∵ The circumference = πd

- Substitute the value of the circumference in the formula

∴ 8.97 = πd

- Subtract both sides by π

∴ 2.855 = d

- Round it to 2 decimal places (to the nearest hundredth)

∴ d = 2.86 cm

The length of the diameter is 2.86 cm rounded to 2 DP

The product of two consecutive integers is 56.find the the integers.
defon

Let, the integers = x,(x+1)

x*(x+1) = 56

x²+x = 56

x²+x-56 = 0

x²+8x-7x-56=0

x(x+8)-7(x+8)=0

x+8= 0  OR x-7=0

x = -8 OR x = 7

it would be -8 & -7 or 7 & 8
