The volume of a cone is one-third of the product of the area of the base times the height, i.e.
(1/3)π(r^2)*h = (1/3)π(3cm)^2 *(8cm) = 75.40 cm^3
Now multiply that by the number of cones: 6 * 75.40 cm^3 = 452.40 cm^3.
Then the answer is 452 cm^3
Answer:
B
Step-by-step explanation:
15 divided by 2.49 equals 0.166 (Approximately 17 cents/oz) whilst 20 divided by 3.32 equals 0.111 (Approximately 11 cents/oz).
Answer:
135 cm²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = 
h(a + b)
where h is the height and a, b the parallel bases
Here h = 9, a = 13 and b = 17 , thus
A = × 9 × (13 + 17)
= 0.5 × 9 × 30
= 135 cm²
2.345 * 10^9 . Hope this helps
Answer:
102 degrees.
Step-by-step explanation:
Because the 3.3's are congruent (the same), this triangle is isosceles.
A property of isosceles means that the two angles are congruent.
39+39= 78
This means that the last angle must be 180-78.
