Part A

Break up the figure into three semicircles and a triangle. Find the area of each piece and then add up the sub-areas to get the total area.

=============================================

Part B

T = Area of Equilateral Triangle
T = 0.25*sqrt(3)*s^2
T = 0.25*sqrt(3)*10^2
T = 43.30127 which is approximate

M = area of one semicircle
M = (area of full circle)/2
M = (pi*r^2)/2
M = (pi*5^2)/2
M = (3.14*5^2)/2
M = 39.25 which is approximate 

There is one triangle and three semicircles, so
A = total area
A = T+3*M
A = 43.30127+3*39.25
A = 161.05127

The total area of the entire figure is roughly 161.05127 square inches

Someone help me fast please. Given the diagram below and DE∣∣∣∣KL, find FE and FL.
stealth61 [152]

Answer:

Part 1) The length of segment FE is 10 units

Part 2) The length of segment FL is 4.8 units

Step-by-step explanation:

we know that

Triangle FED and triangle FKL are similar by AA Similarity Postulate

Part 1) Find FE

Remember that

If two figures are similar, then the ratio of its corresponding sides is proportional

\frac{DE}{KL}=\frac{FE}{FK}

substitute the given values

\frac{15}{6}=\frac{FE}{4}

FE=15(4)/6\\FE=10\ units

Part 2) Find FL

Remember that

If two figures are similar, then the ratio of its corresponding sides is proportional

\frac{DE}{KL}=\frac{FD}{FL}

substitute the given values

\frac{15}{6}=\frac{12}{FL}

FL=6(12)/15\\FL=4.8\ units

Snezhnost [94]

Answer:

A) ≈ 6.93

B) ≈ 0.02

Step-by-step explanation:

A)

Formula : a² + b² = c²

2.4² + 6.5² = c²

5.76 + 42.25 = c²

c = √48.01

c ≈ 6.93

B)

Formula = c² - a² = b²

1/3² - 1/4² = b²

1/9 - 1/16 = b²

b = √7/144

b ≈ 0.02

If my answer is incorrect, pls correct me!
