lions [1.4K]

Answer:

b.

1017 sq. cm

Step-by-step explanation:

Surface area:

The surface area of a sphere with radius r is given by:

S = 4\pi r^2

In this question:

Diameter of 18, since the radius is half the diameter, r = \frac{18}{2} = 9

The surface area is:

S = 4\pi*9^2 = 1017

So 1017 square centimeters, and the best option is b.

La Michoacana has 4 flavors of icecream: mint,chocolate, strawberry, and vanilla. You can havethree scoops. How many variations
lions [1.4K]

Remember that

the formula to calculate the combination is equal to

nCr=n!/[r!(n-r)!]

in this problem

we have

n=4

r=3

substitute the given values

4C3=4!/[3!(4-3)!]

4C3=4!/[3!(1)!]

4C3=4*3!/3!

4C3=12

the answer is 12

For 2 scoops

we have

n=4

r=2

substitute

4C2=4!/{2!(4-2)!]

4C2=(4*3*2*1)/4

4C2=6

the answer is 6
