6.75 Calories/minute is Blake’s unit rate.
Answer:
Option 3. (2π + 40) mm².
Step-by-step explanation:
Area of the composite figure = area of MKCD + area of ABCD + area of semi circle with AB as diameter.
Then Area A = (DC + MK)/2 × DN + AB² + (1/2)×π×2²
= (4 + 8)/2 × 4 + 4² + (1/2)×π×4
= 24 + 16 + 2π = (2π + 40) mm²
Therefore option 3. (2π + 40) mm².

Answer:
The answer instead is 10:14.
Step-by-step explanation:
In this case, there are ten boys and fourteen girls in this class. The ration would then be 10:14. Instead, Jeff said 5:12 which isn't correct. He can correct it by using the number of boys given, find the difference of girls in a class of twenty-four students, and then get his answer!
First, we find the area of the circle.
A = pi * r^2
A = pi * (1 cm)^2
A = pi cm^2
The area of the circle is pi cm^2.
The area of the triangle is also pi cm^2.
Now we use the area of a triangle.
A = (1/2)bh
(1/2)bh = A
(1/2)(3 cm)h = pi cm^2
(3 cm)h = 2pi cm^2
h = (2/3)pi cm
The exact height is 
If you want an approximate height, then it is 2.09 cm.
