Answer:
The area of the circle is 
Step-by-step explanation:
we know that
The area of a circle subtends a central angle of 
radians
so
By proportion find the area of the circle
The slope is approximately 1.7x+5
Answer:
x^2_5+6
=-4^2-5+6
=+16-5+6
=+11+6
=17
Step-by-step explanation:
then the answer is 17
I hope it helps you c:
First, you know that the slope will be the same (3/2).
Plug in the points 0 for x and 7 for y in order to find b.
7=3/2*0+b
b=7
Then put the new slope and y-intercept into the equation:
y=3/2x+7
Answer:
It will take 4 hours to dig in the garden
Step-by-step explanation:
First we have to calculate the diameter, for this we will use the formula to calculate the circumference of a circle and we will clear the diameter
d = diameter
π = 3.14
c = circumference
c = π * d
d = c / π
d = 88yd / 3.14
d = 28.025yd
round to the nearest whole number
28.025 = 28
d = 28yd
To know how many hours it takes, we divide the diameter by the speed
t = time
v = velocity
t = d / v
t = (28yd) / (7yd/h)
t = 4h
It will take 4 hours to dig in the garden
