Answer 1

Answer:

Answer:

$\mathrm{48 \:feet}$

Step-by-step explanation:

Use the Pythagorean theorem.

$a^2+b^2=c^2$

$20^2+b^2=52^2$

$20^2+b^2-20^2=52^2-20^2$

$b^2=2304$

$b=√(2304)=48$

5. What is the area of the figure to the nearest square centimeter? It is composed of a symmetric hexagonand a semicircle 4 cm6 cm3 cm4 cmc 100 cmA 50 cm2D 129 cmB 86 cm

Answers

Area of the given figure is equal to $86\ cm^(2)$ ( nearest square centimeter).

What is area?

" Area is defined as the total space occupied by any two-dimensional object enclosed in it."

Formula used

Area of rectangle = length × width

Area of triangle $= (1)/(2) * base * height$

Area of semi-circle $= (1)/(2) * (\pi r^(2) )$

$r=$ radius of the circle

According to the question,

Given figure is composed of :

two congruent rectangles, four congruent triangles, one semi-circle

Given dimensions,

Length of a rectangle $= 6cm$

Width of a rectangle $= 4cm$

Height of a triangle $= 4cm$

Base of a triangle $= 3cm$

Radius of the semicircle $= (6)/(2)$

$=3cm$

Substitute the value in the formula to get the required area,

Area of a rectangle $= 6 * 4$

$= 24 cm^(2)$

Area of a triangle $= (1)/(2) * 3* 4$

$= 6 cm^(2)$

Area of a semicircle $= (1)/(2) * \pi * 3^(2)$

$=4.5 * 3.14\n\n= 14.13 cm^(2)$

Substitute the value to get the required area,

Area of the given composed figure $= 2* 24 + 4* 6 + 14.13$

$= 48 + 24 + 14.13\n\n= 86.13 \ cm^(2)$

≈ $86 cm^(2)$ (nearest square centimeter)

Hence, Option(B) is the correct answer.

What is 12 divided by 3/4

Answers

12 divided by 3/4 =
16

It is 16 because the reciprocal of 3/4 is 4/3 and 12 as a fraction is 12/1. So 12/1 x 4/3 is 48/3. And if you divide 48 by 3 you will get 16. If you don't get 16 then you did the wrong calculation.

Hope I Helped You!!! :-)

Have A Good Day!!!
