Answer:
25π units^2
Step-by-step explanation:
The shape is a quarter circle with radius 10 units.
area of circle = πr^2
area of a quarter circle = (1/4)π(10 units)^2
area = 25π units^2
Answer:
t=0 and t=5
Step-by-step explanation:
5t = t^2
Subtract 5t from each side
5t-5t = t^2 -5t
0= t^2 -5t
Factor out a t
0= t(t-5)
Using the zero product property
t=0 and t-5 =0
t=0 and t-5+5=0+5
t=0 and t=5
Answer:
tan D = 
or 0.545
tan F = 
or 1.833
Step-by-step explanation:
To find tangent is always 
so the opposite of angle D is line EF which is 4.8 and the adjacent side is line ED which is 8.8 so 
which is or 0.545
The opposite of angle f is line ED which is 8.8 and the adjacent is line EF which is 4.8 so 
is or 1.833
