Answer:

Step-by-step explanation:

area of a circle

$\pi{r}^{2}$

616=3•142×r×r

616/3•142=r^2

196=r^2

r=√196

r=14

d=2r

d=2×14

d=28

Answer:

Step-by-step explanation:

$d=2\sqrt{\frac{A}{\pi}} =2\sqrt{\frac{616}{\pi} }$ ≈ $28.00563cm$

rounding 28.00563 to 28.

So hence, your answer is 28cm

Jamie takes at random a counter from the bag and records the colour. Red : blue : green = 1:3:7 Jamie does this a number of time

Sonbull [250]

Answer: There are 249 times Jamie takes a counter from the bag.

Explanation:

Since we have given that

Ratio of colour of red to blue to green is 1:3:7.

Number of blue counters = 68

Let the total number of times Jamie does from the bag be x.

So, According to question,

$\frac{3}{11}\times x=68\\\\x=\frac{11}{3}\times 68\\\\x=249.33\\\\=249\ approx.$

Hence, there are 249 times Jamie takes a counter from the bag.

ANSWER ASAP GIVING BRAILIEST AND STUFF!

natita [175]

Answer:

24s^2, 54s^2, 96s^2

Step-by-step explanation:

Let s represent the initial side length of the cube. Then the area of each face of the cube is A = 6s^2 (recalling that the area of a square of side length s is s^2).

a) Now suppose we double the side length. The total area of the 6 faces of the cube will now be A = 6(2s)^2, or 24s^2 (a 24 times larger surface area),

b) tripled: A = 6(3s)^2 = 54x^2

c) quadrupled? A = 6(4s)^2 = 96s^2
