Answer:

B. 50.24

Step-by-step explanation:

to find the area of a circle you need to use the formula

a=r²π

since the radius is 4 we put that into the equation, lets use 3.14 for pi

a=(4)²×3.14

always do exponents first

a=16×3.14

a=50.24

guapka [62]

Answer:

Step-by-step explanation:

3000/10=300 300=10% of total missiles

300*3=900(30%) That country (assuming it is Iran) would produce 900 short missiles and 900 medium missiles. 3000-900(2)=3000-1800=1200.

Iran will produce 1200 long range missiles.

For the cost of the missiles,

200,000*900=180,000,000. 300,000*900=270,000,000.

870M-(180M+270M)=870M-450M=420M

420,000,000/1200=350,000.

Long Range Missiles are $350,000 each... got me thinkin bout buying some...
