Question:
1 answer:
The frame can hold a mirror with an area of 78.5 in².
<h3>How to find the area?</h3>
The area for a circle of diameter D is given by the formula:
Where pi = 3.14
Here we know that the diameter is 10 inches, replacing that in the area equation we can get:
So the frame can hold a mirror with an area of 78.5 in².

Answer:
1. L1 =
2. O2 =
Step-by-step explanation:
Given: x =
1. To make L1 the subject of formula;
x =
cross multiply to have;
L2 - L1 = xL1(O2 - O1)
collect like terms,
L2 = xL1(O2 - O1) + L1
factorize the right hand side;
L2 = L1[x(O2 - O1)]
L1 =
2. To make O2 the subject of formula;
x =
cross multiply to have;
L2 - L1 = xL1(O2 - O1)
open the bracket to have;
L2 - L1 = xL1O2 - xL1O1
⇒ xL1O2 = L2 - L1 + xL1O1
O2 =
=
