Answer:
142 cm^2
Step-by-step explanation:
Okay, we can first break this down into 3 different rectangles.
3 x 5 rectangle
16 x 7 rectangle
3 x 5 rectangle.
From here, we just multiply these out and add them. 15 + 15 + 112 = 142. So our answer is 142 cm^2
Answer:
Step-by-step explanation:
-x + 2y = 8
-2x + y = -5
2x - 4y = -16
-2x + y = -5
-3y = -21
y = 7
-x + 14 = 8
-x = -6
x = 6
(6,7)
Answer:
r = 55.2 cm
Step-by-step explanation:
the arc length is calculated as
arc = circumference × fraction of circle
= 2πr × 
( r is the radius )
given arc = 63.48π , then
2πr × = 63.48π ( cancel 2π on numerator/ denominator )
r × 
π = 63.48π ( divide both sides by π )
= 63.48 ( multiply both sides by 20 to clear the fraction )
23r = 1269.6 ( divide both sides by 23 )
r = 55.2 cm
