Answer:
366.5cm³
Step-by-step explanation:
1. Determine the height and radius of cone.
2. Using the formula for the volume of a cone input where there is an h and r.
3.Where it says Area of base, it is talking about the circular base and that you need to find its area. (π×r²), you already have the radius so you put it in the formula and solve (π×5²)
4. Once you have the area of the base you can now completely solve. Multiply ⅓×(78.54)×14
Answer:
24 cm then findthe volume of the balls
Step-by-step explanation:
Answer:
Step-by-step explanation:
The formula of a lateral area of a cone:
r - radius
l - slant height
The formula of a surface area of a cone:
We have r= 9mm and l = 17mm. Substitute:
10.50a + 3.75b = 2071.50
3.75x82 = 307.50
2071.50-307.50 = 1764
10.50a = 1764
a = 1764/10.50 = 168
168 adult tickets were sold
Step-by-step explanation:
when it is phrased like that it should mean that we apply the scale factor to the original images to create the new ones.
and that means the new images will in our case be bigger by the factor of 2.
therefore, the 4th answer option is correct.
2 cm turn into 2×2 = 4 cm
1.5 cm turn into 2×1.5 = 3 cm
3 cm turn into 2×3 = 6 cm
