Answer:
Area is = to 1017.88
Circumference is = to 113.1
Step-by-step explanation:
To find the area of a circle use the formula A=πr2
So . . .
A = π18²
A = π324
A = 1017.88
To find the circumfrence of a circle use formula C=2πr
So . . .
C = 2π18
C= 113.1

4 strips of paneling 40cm long and 4cm wide are arranged to form a square. What is the area of the inner square in cm

Rom4ik [11]

The area of the square will be 640 sq cm.

Step-by-step explanation:

Given,

Number of strip = 4

Length (l) of each strip = 40 cm

Width (b) of each strip = 4 cm

To find the area of the inner square.

Formula

The area of rectangle = l×b

If the area of a square is A, each side will be √A

Now,

Area of each strip = 40×4 sq cm = 160 sq cm

Area of 4 strips = 160×4 sq cm = 640 sq cm

Hence,

The area of the square will be 640 sq cm.

Answer:

10/13

Step-by-step explanation:

There are 52 cards in a standard deck. There are 4 queens (queen of spades, clubs, hearts, diamonds) and 36 (2 - 10 of four suites) number cards. Therefore the probability of drawing a queen or a number card is (4 + 36)/52 = 40/52 = 10/13.

Katena32 [7]

Answer:

By using the pythagorean theorem a^2 + b^2 = c^2

D is the correct answer Where PQ

= √15^2+√19^2

=√ 225 + √361

= √ 586

Length of PQ = √586 = 24.2074368738(ans)

PLZ HELP !! Which of the points (s, t) is not one of the vertices of the shaded region of the

stira [4]

Answer:

A(0,10)

Step-by-step explanation:

Given the 4 inequalities:

s ≥ 12 - 0.5t (1)

s ≥ 10 -t (2)

s ≤ 20-t (3)

s ≥ 0

t ≥ 0

Let analyse all 4 possible answer:

A(0, 10)

Let substitute this point into (1) we have: 10 ≥ 12 -0.5*0 Wrong

We do not choose A

B (0, 20)

Let substitute this point into (1) we have: 20 ≥ 12 -0.5*0 True

Let substitute this point into (2) we have: 20 ≥ 10 - 0 True

Let substitute this point into (3) we have: 20 ≤ 20 - 0 True

We choose B as the vertex

C. (4, 16)

Let substitute this point into (1) we have: 16 ≥ 12 -0.5*4 True

Let substitute this point into (2) we have: 16 ≥ 10 - 4 True

Let substitute this point into (3) we have: 16 ≤ 20 - 4 True

We choose C as the vertex

D. (16,4)

Let substitute this point into (1) we have: 4 ≥ 12 -0.5*16 True

Let substitute this point into (2) we have: 4 ≥ 10 - 16 True

Let substitute this point into (3) we have: 4 ≤ 20 - 16 True

We choose B as the vertex

Hence, the point A(0,10) is not one of the vertices of the shaded region of the set of inequalities.
