Find the radius of a sphere whose surface area is 154 cm\(^2\)?
7.00 cm
3.50 cm
3.00 cm
1.75 cm
Correct answer is B
| 154 = 4 x | 22 | x r\(^2\) |
| 7 |
| 154x7 |
r\(^2\) |
| 4x22 |
√ 49/4 = r
| 7 | = r |
| 2 |
∴r = 3.50

In the figure above , TS//XY and XY = TY, ∠STZ = 34°, ∠TXY = 47°, find the angle marked n?
47o
52o
56o
99o
Correct answer is B
In Δ TYX
XY = TY ∴y =47° base ∠s of ISCΔ
But y+x+34+47 = 180 interior
opposite ∠s are supplementary
47 + x + 34 + 47 = 180
x + 128= 180
x = 180- 128
x = 52°
