Work out the perimeter of this semicircle with radius 3cm. Give your answer in terms of π

kondaur [170]

Step-by-step explanation:

<u>Given </u><u>:</u><u>-</u><u> </u>

A semicircle is given with radius of 3cm .

And we need to find the perimeter of the semicircle . We know the perimeter as ,

$:\implies$ Perimeter = πr

$:\implies$ Perimeter = 3cm × π

$:\implies$ Perimeter = 3π cm .

Now there is the diameter of circle is 6cm . Hence totally the perimeter is ,

$:\implies$ Perimeter = 3π + 6 cm

We were supposed to give answers in terms of π .

<h3>Hence the perimeter is ( 3π + 6 ) cm</h3>

Answer:

$A=189\ mm^2$

Step-by-step explanation:

<u>Surface Areas </u>

Is the sum of all the lateral areas of a given solid. We need to compute the total surface area of the given prism. It has 5 sides, two of them are equal (top and bottom areas) and the rest are rectangles.

Computing the top and bottom areas. They form a right triangle whose legs are 4.5 mm and 6 mm. The area of both triangles is

$\displaystyle A_t=2*\frac{b.h}{2}=b.h=(4.5)(6)=27 mm^2$

The front area is a rectangle of dimensions 7.7 mm and 9 mm, thus

$A_f=b.h=(7.5)(9)=67.5 \ mm^2$

The back left area is another rectangle of 4.5 mm by 9 mm

$A_l=b.h=(4.5)(9)=40.5 \ mm^2$

Finally, the back right area is a rectangle of 6 mm by 9 mm

$A_r=b.h=(6)(9)=54 \ mm^2$

Thus, the total surface area of the prism is

$A=A_t+A_f+A_l+A_r=27+67.5+40.5+54=189\ mm^2$

$\boxed{A=189\ mm^2}$

Tickets to the dinosaurs now exhibit cost $10.50 each and come in a book of 8. how much change will kenny get from $100 if he bu

inn [45]

Answer:

Kenny will get $16 change from $100 if he buys a book of 8.

Step-by-step explanation:

Given cost of each ticket of the dinosaurs now exhibit = $10.50.

Total number of tickets = 8 tickets.

Total amount Kenny has to buy tickets = $100.

He need to buy only 8 tickets.

Total cost of 8 tickets = cost of one ticket × total number of tickets

= 10.50 × 8

= $84.

Therefore cost of all 8 tickets is $84.

Kenny would left money = 100 - 84 = $16.

<h3>Therefore, Kenny will get $16 change from $100 if he buys a book of 8.</h3>
