If the great circle circumference of a sphere is 16pie yards, find its surface area

PSYCHO15rus [73]

Answer:

Step-by-step explanation:

The circumference of a circle = 2*pi * r

so 16 pi yards = 2 * pi * r

Divide both sides by 2

16 pi/2 = 2*pi * r /2

8*pi = pi * r

Divide both sides by pi

8 * pi / pi = pi * r / pi

r = 8

====================

Surface Area = 4 pi * r^2

r = 8

Surface Area = 4 * pi * 64

Surface Area = 256 * pi

Can someone please help me with this question

Elina [12.6K]

Answer:

The answer should be: B

I think it's B because there are 2 cups of water (2c) and 7 bottles of water (7w) which costs $16 so that would be 2c +7w=16. Also for the other one, it's 3 cups (3c) and 8 bottles of water (8W) and the cost is $19 so that would be

3c + 8w =19

Lubov Fominskaja [6]

Answer:

The answer is "0.6227 and 0.5971".

Step-by-step explanation:

$\to p(x\leq 2)=p(0)+p(1)+p(2)$

$=e^{-2.2}(1+2.2^{1}+\frac{2.2^2}{2!})\\\\=0.6227$

$\to x \sim emp(\frac{1}{2.2})\\\\\to f(x)=\frac{1}{2.2} emp1-\frac{x}{2.2}$

$\to p(x \leq 2)=\int^{2}_{0} \frac{1}{2.2} emp1(-\frac{x}{2.2}\ dx$

$=1-emp1-2|2.2\\\\=0.5971$
