Hello from MrBillDoesMath!
Answer:
r = = 57.6 (approximately)
Discussion:
Given: circumference of circle O = 362.14
The circumference of a circle of radius r, is given by the formula C = 2 *PI *2.
So we need to find the value of r in
2*Pi*r = 362.14
Divide both sides by 2*PI to get
r = (362.14)/ (2 * Pi) = (362.14)/ 6.283 (approximately)
= 57.6 (approximately)
Thank you,
MrB
Answer:
A. The length is 1.5 inches and the width is 1 inch.
Step-by-step explanation:
If we assume the two scale factors are related, then 1:10 is half of 1:20, so half of 3:2 is 1.5:1.

Answer:
Step-by-step explanation:
A 45 degree angle in a right triangle produces 2 equal sides. In this case z and the perpendicular line are equal. So that's were we'll start. Then you move on to the 60 degree angle to get x and y.
Finding z
z^2 + z^2 = (24√2) Combine the left
2z^2 = 24^2 * 2 Divide both sides by 2
2z^2/2 = 24^2/2
z^2 = 24^2 Take the square root of both sides
√z^2 = √24^2
z = 24
Finding x and y
The perpendicular = 24. Because it is a 60 degree angle that's given, we can do this without a calculator.
Tan 60 = opposite over adjacent
sqrt(3) = Perpendicular / z Multiply both sides by z
z*sqrt(3) = perpendicular
The above calculation tells us the perpendicular is 24
z*sqrt(3) = 24 Divide by sqrt 3
z = 24/√3
z = 24/1.73
z = 8√3
Finding x
Use Pythagoras to determine x
Perpendicular^2 + (8√3)^2 = x^2
24^2 + 8^2*3 = x^2
576 + 192 = x^2
768 = x^2
√x^2 = √768
x = 27.71
Amayo943,
Remember that with exponents you have to multiply the number of exponets by the same number it's in for example: 
In this case you need to know that:
Therefore your answer is "225."
Hope this helps!
