Answer:
Step-by-step explanation:
11. x = 8*sin60degree = 6.9
12. x = 6*tan30degree = 3.5
13. x = 25 / tan68degree = 10.1
14. x = 9/cos49degree = 13.7
18. LK = sqrt(16^2+24^2-2*16*24*cos29degree) = 12.7
19. m<H = 65.4
20. GF = 26.2
I think you have to divide 275/5 and that will give you his speed for one hour.
Answer: 55 mph
The surface area of a sphere is A = 4 π R² .
Sadly, the question doesn't give you 'R', so you have to
back it out of the circumference.
Circumference = π (diameter)
Divide each side by π : Diameter = circumference / π
Radius = 1/2 diameter: Radius = circumference / (2 π)
Area = 4 π R² =
4 π (circumference/2π)² =
4 π (circumference)² / 4 π²
Divide top and bottom by 4π : Area = (Circumference)² / π
Circumference = 37.68 units
Area = (37.68)² square units /π =
<em>451.93 square units</em>
