Answer:
R = 11.42º
Step-by-step explanation:
sin∅ = opp/hyp
sinR = 20/101
R = arcsin20/101
Use calculator
R = 11.421186274999285
Rounded
R = 11.42º
Answer:
<u>551 square centimeters</u>
Step-by-step explanation:
Finding the radius (r) :
- C = 2πr
- 83.21 = 2 x 3.14 x r
- 83.21 = 6.28r
- r = 83.21/6.28
- r = 13.25 cm
Finding the area :
- A = πr²
- A = 3.14 x (13.25)²
- A = 3.14 x 175.5625
- A = <u>551 square centimeters</u> (nearest whole number)
<u></u>
The area of this hub cap is about <u>551 square centimeters</u>.
The difference is 18/35
hope this is what u r looking for
So i'm assuming your eqtn is h = -16t^2 + 27t + 10
and we're looking for t = ? when h = 0
=> 16t^2 - 27t - 10 = 0
(16t + 5)(t - 2) = 0
t = 2 and t = -5/16
