Answer:

if the question is what is the are of the circle without the rectangle inside it, then we could solve it easily using the Mathematical formula for A Circle's area which is

$\pi {r}^{2}$

since a radius is half a diameter, and the diameter is 8cm, the radius becomes 4 cm

Step-by-step explanation:

π×4^2

3.14×16

50.24

what is the probability that a number selected at random from the set {2,3,7,12,15,22,72,108} will be divisible by both 2 and 3?

evablogger [386]

First, look at how many numbers are divisible by 2 and 3.
12,72, and 108 and are all divisible by both 2 and 3. That makes 3 out of 8 numbers.
Depending on what form you have to put the probability, that makes it 3:8, 3 out of 8, or 37.5% probability.

Which expression is equivalent to 2x + x^2 + 3x + 5x^2 - 10x?

Nonamiya [84]

2x + x² + 3x + 5x² - 10x (combine like terms)
6x² + 5x -10x
6x² - 5x
which is the same as
-5x +6x²
Your answer is C

Answer:

r = 6

Step-by-step explanation:

To get the value of r we will use the pythagoras theorem a shown;

PR² = QR² + PQ²

(4+r)² = 8² + r²

Expand

16+8r+r² = 64 + r²

16 + 8r = 64

8r = 64 - 16

8r = 48

r = 48/8

r = 6

Hence the value of r is 6
