Answer:
51 inches
Step-by-step explanation:
The centroid G divides each median into the ratio 2:1, so GF is 1/3 of CF. That is, ...
CF = 3(GF) = 3(17 in)
CF = 51 in
Answer:
2.)70
4.)451,17
Step-by-step explanation:
2.)
a1 = 8*5 = 40
a2 = ((20-8)*5)/2 = 30
aTotal = 40+30 = 70
4.)
a1 = 18*18 = 324
a2 = (πr²)/2 = 127,17
aTotal = 127,17 + 324 = 451,17
Answer:
a. 9m
Step-by-step explanation:
Pi = 3.14 = 22/7
formula :
Area of a Sector of a Circle = (central angle)/360 * πr² =
(central angle)/360 * πr² = Area of a Sector of a Circle
43/360 * Pi * r^2 = 30.39
r^2 = (30.39 * 360) / (Pi * 43)
r^2 = (30.39 * 360) / (22/7 * 43)
r = √ (30.39 * 360 * 7) / (22 * 43)
r = √76582.8/946
r = √80.9543340381
8.99746264444 which is roughly
9
