Log(ab)=log(a)+log(b)
log_a(a)=1
so
log_a(a)=1
so
Mattie and Matilda are at a bead class making bracelets. If Matties wrists bracelet has a circumference of 7 inches and Matilda
1 answer:
The radius of Matilda's bracelet is 2.784 inches
Step-by-step explanation:
Given,
The circumference of Matties bracelet is = 7 inches
The bracelet of Matilda is 2.5 times of Matties's bracelet
So, the circumference of Matilda's bracelet = 2.5 × 7 inches = 17.5 inches
To find the radius of Matilda's bracelet
Formula
The circumference of circle of radius(r) = 2πr inches
According to the problem,
2πr = 17.5
or, r =
= 2.784 inches (approx)

Triangle is missing, so i have attached it.
Answer:
Radius = 10.82
Step-by-step explanation:
From the image attached, the triangle is obviously a right angle triangle and therefore, the missing side (AB) which is the radius can be found via pythagoras theorem.
We are given;
AC = 21
BC = 18
Thus;
|AC|² = |AB|² + |BC|²
21² = |AB|² + 18²
|AB|² = 441 - 324
AB = √117
AB = 10.82
