Answer:

314 \frac{2}{7} cm^{2}

Step-by-step explanation:

Surface area of sphere= 4πr², where r is the radius of the sphere.

Given that the diameter is 10cm,

2(radius)= 10cm

radius= 10 ÷2

radius= 5cm

Surface area of sphere

slega [8]
The sticker price of the car can be calculated by deducting from the msrp (manufacturer's suggested retail price) the sport package price, stereo package price and the destination charge.

                     sticker price of the car = ($19,150) - ($2500 + $600 + $600)
                     sticker price of the car = $15,450

<em>Hence, the sticker price of the car is $15,450. </em>

Vlad1618 [11]

Answer:

It's very simple. In 4 decimal digits there are 10,000 (0000 to 9999) possible values. The odds of any one of them coming up randomly is one in 10,000. A specific "4 digit number" would have 1/9000 chance, since there are 9000 4 digit numbers (1000-9999).
