C = 3.14 x 2r

88 = 3.14 x 2r

28 = 2r

14 = r

A = 3.14 x r^2

A = 3.14 x 14^2

A = 615

Answer:

A =  617 yd², to the nearest yard

That distance is called the "circumference," and its formula is C = 2πr.

We need r to find the area of the park.  So we solve C = 2πr for r:

          C

r   = -------    

        2π

Substituting 88 yd for C, we get r = (88 yd) / (6.28) = 14.01 yd

The formula for the area of this circular park is A = πr².

Here, r = 14.01 yd, so the area of this park is:

A = π(14.01 yd)² = 3.14(196.36 yd²) = 617 yd², to the nearest yard.

PLEASE HELP ME ON 6-11 AND SHOW WORK PLEASE!!

Answer:

6) 6\sqrt{2}

9) 40

10) \frac{5\sqrt{2} }{2}

11) 13

Step-by-step explanation:

6)A right triangle rule: if 2 legs are equal, the hypotenuse is the length of that leg*\sqrt{2}

9) Pythagorean Theorem

a^{2} +b^{2} =c^{2}

We know the hypotenuse (41) so we substitute that for c and 9 for b now we need to find a

\sqrt{41^{2}-9^{2}  } which gives us 40

10) same with #6 but we do the opposite. SInce we have the hypotenuse, we can divide that by \sqrt{2} because we know that if 2 legs are equal, the hypotenuse is multiplied by \sqrt{2}. Multiply the numerator and denominator by \sqrt{2} because we can't have a square root in the denominator.

11) like #9 we have the a and b but we need to find c

a=5 b=12 c=r

so \sqrt{5^{2}+12^{2}  } which gives us 13
