Answer:

Step-by-step explanation:

area of a cylinder = (area of a circle) times the (height)

area of a cylinder = π radius² × height

radius = 57 cm height = 40 cm

area of a cylinder = π 57² cm² × 40 cm

= π (57² × 40) cm³

= π ( 57 × 57 × 40) cm³ 57x57 = 399 + 2850 = 3249

= π (3249 × 40) cm³

= 129969π cm³ π = 3.14

= 129969 × 3.14 cm³

= 408,074.4 cm³ < ----------------- Final Answer

Nataliya [291]

Answer:

a) $P($

b) $n=(HHH, HHT, HTH, HTT, THH, THT, TTH, TTT).$

Step-by-step explanation:

From the question we are told that:

3 coin are tossed

Therefore

Sample space $n=(HHH, HHT, HTH, HTT, THH, THT, TTH, TTT).$

Generally the sets that correspond with the result of at most one tail is therefore given as follows

$P($

Therefore

The result is at most one tail when

Find the distance between these points. A(5,8), B(-3,4)

konstantin123 [22]

Answer:

Distance between the points is 8.94 units

Step-by-step explanation:

General formula:

${ \boxed{ \bf{distance = \sqrt{ {(x_{1} - x _{2} )}^{2} + {(y _{1} - y _{2} ) }^{2} } }}}$

substitute:

${ \sf{ = \sqrt{ {(5 - ( - 3))}^{2} + {(8 - 4)}^{2} } }} \\ = { \sf{ \sqrt{64 + 16} }} \\ = { \sf{ \sqrt{80} }} \\ = 8.94 \: units$

Ne4ueva [31]

Mr.Jones charges $800 per lesson and requires 3 lessons

That means mr Jones will charge Samantha 800x3 = $2400 in total.

Mr. Police charges $62 per lesson and requires 4 lessons,

62x4 = $248 in total.

Since mr. Police charges less than mr.Jones, it would be a better deal for Samantha.

IN CASE YOU WROTE THE QUESTION WRONG AND MR JONES CHARGES $80 PER LESSON

In that case it would be 80x3 = $240 in total

mr jones would charge less now and it would be better deal for Samantha.

babunello [35]

Answer:

Step-by-step explanation:

We can solve this question using proportion

Perimeter of the square/Time is takes to unlock

We are told in the question that:

The cellphone unlocks when the perimeter reaches 32 centimeters, taking a total of 2.5 seconds.

Hence, the perimeter of the square after 1.5 seconds is:.x = unknown

32/2.5 = x/1.5

Cross Multiply

2.5x = 32 × 1.5

x = 32 × 1.5/2.5

x = 19.2 centimeters
