There are enough information's already given in the question. Based on those information's that answer can be easily deduced.
Radius of the sphere = 8 units
Then
Surface area of the sphere = 4 *pi * r^2
= 4 * pi * (8)^2
= 4 * pi * 64
= 256pi
I hope that this answer has come to your help.
Answer:
It takes aditi 5 hours to walk 17 miles.
Step-by-step explanation:
First, find her speed in miles per hour.
1.7 miles in half an hour.
1.7 * 2 = 3.4
3.4 miles per hour.
To find the time, use the distance formula.
Distance = rate * time
17 = 3.4 * time
17/3.4 = time
5 = time
Answer:
Step-by-step explanation:
Answer:
1) x = 6.6.
2) x = 6.1.
Step-by-step explanation:
1) In this triangle, the hypotenuse is given, which is 8 units, and the angle is given, which is 35 degrees. The base is unknown. To find the base, following ratio will be used:
cos θ = Base/Hypotenuse.
cos 35 = x/8.
x = 8*cos 35.
x = 6.6 units (to the nearest tenth)!!!
2) In this triangle, the base is given by 12, and the angle is given by 27 degrees. The perpendicular is unknown. To find the perpendicular in this case, tangent formula will be used:
tan θ = Perpendicular/Base
tan 27 = x/12.
x = 12*tan 27.
x = 6.1 units (to the nearest tenth)!!!
