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)
Answer:
20 years
Step-by-step explanation:
Using the formula; A = P(1 + r)^t
We can plug in the known to find t
400 = 220(1.03)^t
then solve for t;
1.818 = 1.03^t
Introducing In
In 1.818 = t × In (1.03)
t = 20.225
t = 20 years to the nearest year
Answer:
2258 cu. units
Step-by-step explanation:
you take 22/7 multiply by radius squared and multiply that by 5
101.15
Explanation:
140 x 7.25% = 10.15
140 x 35% = 49
Then we add the tax and subtract the sale :
140 + 10.15 - 49 = 101.15$
Hope it’s right
