Answer:
There is an error in the question.
All angles in an equilateral triange are 60º
The answer is 30, hope this helps.
The 4 is in the ten thousands place
For question one, you would need to use the formula pi r ^2. So first you have 4.5, which is your radius(stands for r). Then you square it, which is 20.25. Then, you multiply 20.25 with pi. Then for circumference, you do 2 x pi x the radius which is 4.5. So for area, you get 63.62. Then for circumference you get 28.27.
For question 2, it is basically the same steps but instead you a diameter, not a radius. To get the radius, divide by 2, which the radius will be 6. Then from there, the radius is 6, and you solve the question.
Answer:
m = -24
Step-by-step explanation:
(m/6) - 7 = -11
Add 7 to each side
(m/6) - 7+7 = -11+7
m/6 = -4
Multiply each side by 6
m/6 *6 = -4*6
m = -24
