Answer:
14m
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
153.86 = 3.14 r^2
Divide each side by 3.14
153.86 /3.14 = r^2
49 = r^2
Take the square root of each side
sqrt(49) = sqrt(r^2)
7 = r
We want the diameter which is twice the radius
d = 2r
d =2*7
d =14
Answer:
she has 2/3 cup left
Step-by-step explanation:
1 and 2/3 + 2/3 =2 and 1/3 what is left??
2/3
Yes the answer is 24 cm2
because the width is 4 cm then 2 width = 2(4) = 8 cm
perimeter = 20 cm
20-8=12 cm
so 12 cm left is 2 length then the length is 12/2= 6;cm
that's why the area is 4*6= 24 cm2
