A farmer has three silos. The largest silo has a diameter of 24 feet. The radius of the smallest silo is one-thrid as big as the diameter of the largest. The middle sized silo has a radius that is 2 feet greater than the radius of the smallest silo. What is the circumference of each silo?

Exact:

Approximate:

50.3 ft, 62.8 ft, 75.4 ft

Step-by-step explanation:

Let's find the radius of each silo using the given information.

"The largest silo has a diameter of 24 feet."

"The radius of the smallest silo is one-third as big as the diameter of the largest."

"The middle-sized silo has a radius that is 2 feet greater than the radius of the smallest silo."

The three radii are: 8 ft, 10 ft, and 12 ft.

Now we use the circumference formula with each radius to find the circumferences.

Middle:

Largest:

The circumferences above are exact. If you want approximations, then use a calculator and an approximation for pi.

The circumferences are approximately: 50.3 ft, 62.8 ft, 75.4 ft

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i
