Circumference of a Circle,C=2πr
π=3.14
r= of the circle
Area of the circle= πr²
We know that
Area= 49 π²
πr²=49
r²=49/π
=49/3.14
=15.60
r= √15.60
=3.9 units
Circumference of a Circle,C=2πr
=2*3.14*3.9
=24.492 units
3 and 32
Step-by-step explanation: 32 *3 equals 96
Answer:
slope=1/3
Step-by-step explanation:
the equation is in slope-intercept form (y=mx+b) and m always equals slope in that equation, so in your equation m=1/3, so slope=1/3
Answer:
4.80 mm to 2 d.p
Step-by-step explanation:
w = f(r)
f'(r) = (dw/dr) = (0.0218 mm/mm)
So, for a small difference in rainfall of 220 mm, what is the corresponding small difference in width of leaves in the two forests given.
One definition of a derivative or a rate of change is that it is the ratio of very small differences in the dependent variable to very small differences in the independent variable.
Mathematically,
(dw/dr) = (Δw/Δr) for very small Δw and Δr.
0.0218 = (Δw/220)
Δw = 0.0218 × 220 = 4.796 mm = 4.80 mm to 2 d.p
Hope this Helps!!!
Hello!
To find our answer, we just divide.
57/60=0.95
We multiply by 100 to find our percent
100(0.95)-95
Therefore, our answer is 95%
I hope this helps!
