Known :
Sa = 1017.36 yd²
Asked :
r = ...?
Answer :
Sa = 4πr²
1017.36 = 4 × 3.14 × r²
1017.36 = 12.56 r²
r² = 1017.36 ÷ 12.56
r² = 81
r = √81
r = <u>9</u><u> </u><u>yd</u>
So, the radius is 9 yd (D)

Answer:
a = 0.4 and b=1.6
Step-by-step explanation:
Both expressions are simply divided
(2x + 8y = 60) ÷ (ax + by = 12)
60÷12 = 5, Hence coefficient of x and y in the bigger equation is divided by 5 to find a and b
2/5 = 0.4 = a
8/5= 1.6 = b

The length of segment BC can be determined using the distance formula, wherein, d = sqrt[(X_2 - X_1)^2 + (Y_2 - Y_1)^2]. The variable d represent the distance between the two points while X_1, Y_1 and X_2, Y_2 represent points 1 and 2, respectively. Plugging in the coordinates of the points B(-3,-2) and C(0,2) into the equation, we get the length of segment BC equal to 5.
