Answer:
140
Step-by-step explanation:
<u>As per picture:</u>
∠PTQ and ∠RTS are vertical angles and they are equal
- ∠PTQ = (x + 28)°
- ∠RTS = (2x + 16)°
- ∠PTQ = ∠RTS
- x + 28 = 2x + 16
- 2x - x = 28 - 16
- x = 12
∠PTR is supplementary with ∠PTQ and their sum is 180°
- ∠PTQ = 12 + 28 = 40°
- ∠PTR = 180 - 40 = 140°
For this we start by putting km into cm
53.23 x 100,000 = 5,323,000
Now we divide by 53 to see the total number of revolutions
5,323,000 / 53 = 100,433.962 revolutiona
Answer:
i=7.6h, 60.8 inches (B)
Step-by-step explanation:
If r is the radius of a sphere its surface area = 4(pi)r^2.
If the radius is doubled then its surface area = 4(pi)(2r)^2 = 4*4(pi)r^2.
So the surface area becomes 4-fold or the increase in surface area is 300%.
