Answer:
1) 188.4 in³
2)306 in³
3)210in³
Step-by-step explanation:
1) r = 5in h = 12in
5 * 12 * 3.14
2) L = 3 W = 8.5 H = 12
3 * 8.5 * 12
3)
( B = 5 W = 7 H = 12)
.5(5 * 7 * 12)
Answer:
1:2 and 4:6 which equal 3:10
Hope I Can Help!! :) Good Luck
x + 30 = 2x (since angleA = angle D, due to congruency between the two triangles.)
30 = 2x - x
30 = x
