68.56 or 69 rounded I just multiplied 14cm and 4 for the area of the rectangle and multiplied 4 by pi since the radius was 2 and the exponent was two it equaled four look at the picture if you don’t understand
The ratio of $2 to $5 is 3: 1
3x$2 + 1x$5 = $11
A set of 3 $2 and 1 $5 gives you $11.
Assumed all 160 coins are $1
Total value = $100
Difference in the value = $300 - $100 = $200
Difference in the $1 and the set of $2 and $5 = $11 - $1 = $10
Number of set of $2 and $5 = $200 ÷ $10 = 20
Calculate the number of $2 and $5 in the 20 sets:
Number of $2 = 3 x 20 = 60
Number of $5 = 1 x 20 = 20
Number of $1 = 160 - 60 - 20 = 80
Answer: There are 80 $1, 60 $2 and 20 $5.
Answer:
The height of the smaller cone is 19.52 cm
Step-by-step explanation:
Given that,
The volume of cone 1, V₁ = 3970 cm³
The volume of cone 2, V₂ = 3100 cm³
The height of the larger cone, h₁ = 25 cm
We need to find the height of the smaller cone. Let it is h₂. For similar cones,
Put values,
So, the height of the smaller cone is 19.52 cm.
B. 113.04
we know this by using the area method A=(pie)r^2
you add 6 into the r so (pie)6^2 wich equals 113.04
