A fireplace arch is to be constructed in form of a semiellipse. The opening is to have a height of 2 feet at the center and a width of 6 feet along the base. The contractor cuts a string of a certain length and nails each end of the string along the base in order to sketch the outline of the semiellipse. 1. What is the total length of the string?

2. How far from the center should the string be nailed into the base?

The total length of the string is 7.85 feet and  the center should be 2.236 feet far the string be nailed into the base

Step-by-step explanation:

Circumference of ellipse =

Circumference of semi-ellipse =

we are given that The opening is to have a height of 2 feet at the center and a width of 6 feet along the base.

So,

Circumference of semi-ellipse =

Distance from center =

Hence the total length of the string is 7.85 feet and  the center should be 2.236 feet far the string be nailed into the base
