For the figures below, assume they are made of semicircles, quarter circles and squares. For each shape, find the area and perim

ICE Princess25 [194]

Answer:

Part a) The area of the figure is $\frac{9}{2}(4+\pi )\ cm^{2}$

Part b) The perimeter of the figure is $3(2+2\sqrt{2}+ \pi)\ cm$

Step-by-step explanation:

Step 1

Find the area of the figure

In this problem we have that

The figure ABC is the half of a square and the other figure is a semicircle

Find the area of the figure ABC

we have

$AB=6\ cm, BC=6\ cm$

The area of the half square ABC is equal to find the area of triangle ABC

$A1=\frac{1}{2}*6*6=18\ cm^{2}$

Find the area of the semicircle

The area of the semicircle is equal to

$A2=\pi r^{2}/2$

we have that

$r=6/2=3\ cm$

substitute

$A2=\pi (3)^{2}/2$

$A2=(9/2) \pi\ cm^{2}$

The area of the figure is equal to

$18\ cm^{2}+(9/2) \pi\ cm^{2}= \frac{9}{2}(4+\pi )\ cm^{2}$

Step 2

Find the perimeter of the figure

The perimeter of the figure is equal to

$P=AB+AC+length\ CB$

we have

$AB=6\ cm$

Applying Pythagoras theorem

$AC=\sqrt{6^{2}+6^{2}}\\AC=6\sqrt{2}\ cm$

Remember that

the circumference of a semicircle is equal to

$C=\frac{1}{2}2\pi r=\pi r$

$r=6/2=3\ cm$

$C=\pi(3)$

$C=3 \pi\ cm$

The perimeter of the figure is equal to

$P=6\ cm+6\sqrt{2}\ cm+3 \pi\ cm$

Simplify

$P=3(2+2\sqrt{2}+ \pi)\ cm$

Divide. 15÷ −5 Drag and drop the correct number into the box to complete the sentence. The quotient is [blank] plz explain so i

KIM [24]

The answer is A. -3 and its a negative result cause that's how it is, like for ex, -15/3 = -5 or 15/-3 = -5 is a negative, and when two positive numbers are divided, the answer is a positive number 15/3 = 5.

Five less than the product of 6 and a number is equal to 8.

schepotkina [342]

Answer:

2.16

Step-by-step explanation:

Hey so we know that product means multiplication and “less than” means subtraction

5 less than=5-

Product of 6 and a number=6*x

6x-5=8

(Since it says 5 less than a product of 6 and a number, we know that we have to subtract 5 from 6x, NOt the other way around)

Add 5 on both sides:

6x=13

Divide by 6

X=2.16

Hope this helps!
