Answer:
the answer is d!
Step-by-step explanation:
because the radius is measuring the distance from any point on the circle to the very center of the circle
Answer:
The radius would be 12cm
and the height 4
gives u the surface area of 1206cm^3
Step-by-step explanation:
Because the triangle is an equilateral triangle, you know that all of the angles are equal to 60°. That means that you can use trigonometry to find the height, which would be sin(60) × 20 = 17.32.
Again, because it is an equilateral triangle, all sides are equal as well, meaning that the base is also 20cm. To find the area of the triangle, we must do (20 × 17.32)/2 = 173.2cm^2, which is the area.
I hope this helps!
