Answer:

the approximate area of this circle is 200.96 inches long.

Step-by-step explanation:

To answer this problem we need to remember that the area of a circle is given by the formula:

Area = πr^2 where r is the radius.

and the perimeter is:

Perimeter = 2πr

Now, the problem tells us that the circle is enclosed by a piece of rope that's 50.24 inches long. So the perimeter of the circle is 50.24 inches.

Since we have the value of the perimeter and the value of pi, we are going to substitute these values in the perimeter formula to find r.

Perimeter = 2πr

50.24=2(3.14)r

50.24= 6.28r

50.24/6.28= r

8= r

Thus, the radius of the circle is 8 inches long.

Now, we can use this value to find the area of the circle:

Area = πr^2

Area = π8^2

Area = 3.14 (64)

Area = 200.96

Therefore, the approximate area of this circle is 200.96 inches long.

Your equation is 3(8-4)+2*5.5
you want to follow PEMDAS
Parenthesis 
Exponents
Multiplication
Division
Addition
Subtaction

so first you will solve the parenthesis (8-4) = 4
put it into your exquation
3(4)+2*5.5

now the next thing we have is multiplication

3(4) = 12
2*5.5 = 11

now plug it into the equation 

12+11=?

now you just do the addition 

your answer should be

What does a equal in 1/2(a-7)=33?​
Dmitriy789 [7]

To find a, you need to isolate/get the variable "a" by itself in the equation:

\frac{1}{2} (a-7)=33    Multiply the inverse of 1/2, which is 2, to get rid of the fraction

(2)\frac{1}{2}(a-7)=(2)33

a - 7 = 66      Add 7 on both sides to get "a" by itself

a - 7 + 7 = 66 + 7

a = 73
