Hello!
The volume of a cone is found by using the formula: V = 1/3πr²h.
Figure 1 --
From figure one, it shows us the radius, which has a length of 8 centimeters, and the height, which is 14 centimeters. With that values, we can substitute those values into the formula and solve.
V = 1/3π(8)²(14)
V = 1/3(64)(14)π
V = 64/3(14)π
V = 896/3π centimeters³, 938.29 centimeters³ (multiplied by π), and 937.81 centimeters³ (multiplied by 3.14).
Therefore, the volume of the first cone is 938.29 centimeters³.
Figure 2 --
From the second figure, the height of the cone is 19.6 and the diameter is 12. To find the radius, divide the radius by 2, which is will give the radius.
V = 1/3π(6)²(19.6)
V = 1/3(36)(19.6)π
V = 12(19.6)π
V = 235.2π, 738.53 (multiplied by 3.14), 738.90 (multiplied by π)
Therefore, the volume of the second cone is 738.90 units³.
Answer: 10,185 registered female doctors.
Step-by-step explanation: We basically want to find how many females were doctors, if 19.4% of the 52,500 females were registered doctors. Basically we want to find 19.4% of 52,500. We will write an equation that works to solve this problem.
19.4/100 = x/52,500 (This equation represents that 19.4% out of 100% is x out of the 52,500 registered doctors.) Solve for x.
19.4/100 x 52,500 = x/52,500 x 52,500.
(19.4 x 52,500 = 1,018,500/100 = 10,185. And, x/52,500 x 52,500 = x.
10,185 = x.
So, 19.4% of all registered doctors would be 10,185 females out of 52,500 females.
You want to compute the total area of the figure. The figure is composed by four 6x4 rectangles, and two 4x4 squares.
The area of one rectangle is 
The area of one square is 
You have four rectangles and two squares, so the answer is
