Use the formula V = length * width * height to find the volumes of each block, then add them together to get the combined volume. So, (5 * 4 * 5) + (4 * 5 * 2) = 140 inches cubed, which is the combined volume.

Hopefully this helps- let me know if you have any questions!

a circle has a radius of 7ft. Find the radian measure of the central angle 0 that intyercepts an arc of length 16ft

Iteru [2.4K]

Answer:

2.29 rads

Step-by-step explanation:

The length of the arc of a circle of radius r is given by;

l = rθ ---------------------------(i)

Where;

l = length of the arc

θ = central angle o that intercepts that arc and measured in radians.

From the question:

l = 16ft

r = 7ft

Substitute these values into equation (i) as follows;

16 = 7θ

Make θ subject of the formula

θ = $\frac{16}{7}$

θ = 2.29

Therefore, the radian measure of the central angle is 2.29 rads

Tameka bought three dozen donuts to take into work. There are 15 cake donuts, 6 glazed donuts, 6 chocolate donuts, and 9 blueber

Leya [2.2K]

Ratio of Cake Donuts to Total Donuts = 15/36

Let, the number of people with Cake donuts = x

Then, 15/36 = x/12

x = 12/36 * 15

x = 1/3 * 15

x = 5

In short, Your Answer would be: 5

Hope this helps!
