Answer:
where is the pic?? i dont see it
Step-by-step explanation:
Use this formula: A= 550(1.048)^9*4 adn then add 9*4*50=1800 which will equal:
4774.191066
<u>The expression that represents the volume of </u><u>the cone is 6aπ.</u>
What is called cone?
- A cone is a three-dimensional shape in geometry that narrows smoothly from a flat base (usually circular base) to a point(which forms an axis to the center of base) called the vertex.
- The volume of a cone is expressed as;
- V = (1/3)πr²h
- Where r is the radius, h is height and π is pie
Given the data in the question;
Radius r = 3
Height h = 2a
Volume of the cone V = ?
We substitute our given values into the expression above.
V = (1/3) × π × r² × h
V = (1/3) × π × (3)² × 2a
V = (1/3) × π × 9 × 2a
V = 18aπ / 3
V = 6aπ
Therefore, the expression that represents the volume of the cone is 6aπ.

Answer:
Isosceles and acute
Step-by-step explanation:
(x+30)+(4x+30)+(10x-30) = 180
15x+30 = 180
15x = 15
x = 10
x+30 = 40
4x+30 = 70
10x-30 = 70
Two equal angles means isosceles. The third angle is less than 90° so the triangle is also acute.
