Your answer is j = 26
Answer:
The diameter is two times the radius, or 2r. The radius of this circle is 7 inches, so the diameter is 2(7) = 14 inches. The diameter is 14 inches.
Step-by-step explanation:
Answer: 75.8
Step-by-step explanation:
Answer:
s = 1.35 (See explanation!)
Step-by-step explanation:
To write an equation, you need to know that all four sides of a square are equal. Since each side is equal, it can be represented by the same variable or value. I'll use s for the variable:
Equation:
4s = 5.4
Note: the 4s is the total perimeter (4 * side)
Now, solve:
4s = 5.4
Divide by four to isolate the s:
4s/4 = 5.4/4
Finally:
s = 1.35
Ok so the formula for this is A=1/2bh lets plug it in.
A=1/2*16*8
A=8*8
A=64 in^2
