The area of figure ABCDEF can be computed as the sum of the areas of trapezoid ACDF and triangle ABC, less the area of trangle DEF.
  trapezoid ACDF area = (1/2)(AC +DF)·(CD) = (1/2)(8+5)(6) = 39
  triangle ABC area = (1/2)(AC)(2) = 8
  triangle DEF area = (1/2)(DF)(2) = 5

Area of ABCDEF = (ACDF area) + (ABC area) - (DEF area) = 39 +8 -5 = 42

The actual area of ABCDEF is 42 square units.

Answer:

<h3>\boxed{ \bold{ \huge{ \boxed{ \sf{ {12.56 \:  {mm}^{2} }}}}}}</h3>

Step-by-step explanation:

Given,

Radius ( r ) = 2 mm

pi ( π ) = 3.14

<u>Finding </u><u>the </u><u>area </u><u>of </u><u>circle </u><u>having </u><u>radius </u><u>of </u><u>2</u><u> </u><u>mm</u>

Area of circle \sf{ = \pi \:  {r}^{2} }

plug the values

⇒\sf{3.14 \times  {2}^{2} }

Evaluate the power

⇒\sf{3.14  \times 4}

Multiply the numbers

⇒\sf{12.56 \:  {mm}^{2} }

Hope I helped!

Best regards!!

MakcuM [25]

Answer:

4. A​ post-lunch nap decreases the amount of time it takes males to sprint 20 meters.

Step-by-step explanation:

This question wants us to state the claim and the hypothesis.

This researchers claim can be found in the first sentence of this question.

Claim: post lunch nap decreases the time it takes to run for 20 meters.

The correct answer option for the claim is the 4th answer option. And it means that sleeping after lunch reduces the time it takes males to run in a 20m race.

B. Hypothesis

H0: Ud <= 0

H1: Ud > 0

d = is the race time without a nap - race time with a nap
