x = 5i x =-5i

Step-by-step explanation:

x^2+25=0

Rewriting

x^2 - (-25)=0

Writing as the difference of squares

a^2 - b^2= (a-b) (a+b)

where a = x and b = (sqrt(-25)) =±5i

( x-5i) ( x+5i) =0

Using the zero product property

x-5i =0 x+5i =0

x = 5i x =-5i

A roof in the shape of a half-cylinder covers the a local soccer field so kids can play soccer

leonid [27]

Answer:

6,280 ft³

Step-by-step explanation:

To find lateral surface area, use the formula L = 2 $\pi$ rh, then plug in the values:

L = 2(3.14)(25)(80)

L = 12,560 ft³

Since its a half cylinder, we have to divide this by 2:

12,560/2 = 6,280

So, the lateral area of the roof is 6,280 ft³
