The formula for area of a circle is: πr^2
r is half the diameter.
FE is the diameter: r = 20/2 = 10
Area of circle using FE = π10^2 = π * 100 = 314 square meters.
BE is a radius:
Area = π3.5^2 = π * 12.25 = 38.465 = 38.5 square cm ( rounded to nearest tenth).
AB is a radius:
Area = π11^2 = π * 121 = 379.94 = 380 square feet ( rounded off).
EF is a diameter
r = 12/2 = 6 meters
Area = π6^2 = π * 36 = 113.04 = 113 square meters ( rounded off).
Answer: she would need four and a half cups more of sugar.
Step-by-step explanation:
You have to add together all of them sugar she would have needed so (1 1/4 times 4) and then subtract what she already had and that gives you 4 and 1/2 cups she would need. Hope this helps
Equilateral- all sides are the same
Answer:
t = 0, 1, 4, 8
h = 0, 12, 0 , 18
Step-by-step explanation:
t = 0 + 1 + 3 + 4
/ x1 - 5 (2) x + 4x + 9
h = 0, 12, 0, 18
After 18 seconds the ball attains...
x/3 = 1/4 - 4x 2(7) = 9/2 - 2 / 4 (0)
