Answer:
44m
Step-by-step explanation:
A = r² = 154
= 22/7 * r² = 154
= r² = 154 * 7/22
= r² = 49
= r = √49
= r = 7m
Perimeter of circle = 2r
= 2 * 22/7 * 7
= 44/7 * 7
= <u>44 m</u>

Answer:
x = 1
y = 5
Step-by-step explanation:
You can use either substitution or elimination for this problem. I will use substitution.
Step 1: Replace x in the 1st equation
-10(y-4) + 3y = 5
-10y + 40 + 3y = 5
-7y = -35
y = 5
Step 2: Plug <em>y </em>into an original equation to find <em>x</em>
x = 5 - 4
x = 1
And you have your final answers!
<span>Remember to place a zero in the quotient when the divisor is larger than the dividend.Place the decimal point in your quotient.Check your answer: Multiply the divisor by the quotient to see if you get the dividend.</span>
(-1, 3)
this is because in a coordinate plane, using the coordinates you gave it is the missing vertice is (-1,3)
