How do you work this out

Digiron [165]

Check the picture below.

notice, is just a circle inscribed in a square.

now for the first one, we know the diameter is 14, so the square is a 14x14, and the radius of that is half the diameter or 7.

now, if we get the area of the square, which includes the area of the circle, and THEN get the area of the circle and subtract it from the square's, what's leftover is the shaded section.

$\bf \textit{area of a circle}\\\\ A=\pi r^2\\\\
-------------------------------\\\\
\stackrel{\textit{square's area}}{14\cdot 14}~-~\stackrel{\textit{circle's area}}{\pi 7^2}\implies 196-49\pi$

now, for the one on the right-hand-side, the radius is 8, and square's area is 16x16,

$\bf \stackrel{\textit{square's area}}{16\cdot 16}~-~\stackrel{\textit{circle's area}}{\pi 8^2}\implies 256-64\pi$

A large drain and a small drain are opened to drain a pool. The large drain can empty the pool in 2 h. After both drains have be

Over [174]

Answer:

Step-by-step explanation:

Let X be the time for only a small drain, the work completed would be unity.

The small drain has been open for a total of 11 hours, one hour next to the large one, and 10 hours alone.

We have that large drainage can accomplish this in 2 hours.

We have the following system:

1/2 + 11 / x = 1

solving, we have:

11 / x = 1 - 1/2

11 / x = 1/2

x = 11 * 2

x = 22

I mean it would take a total of 22 hours for the small drain alone

Mrs.Roberts sewed m shirts using 2 yards of cloth for each shirt.She also sewed (m +2) dresses,using 5 yards of cloth for each d

topjm [15]

Answer:

(7m + 10) yards of cloth was used

Step-by-step explanation:

This is a multiplication problem. Firstly, we are told that she sew m shirts and she used 2 yards of cloth for each of the shirts. The total amount of materials used here is m * 2 = 2m yards

She also sew another (m + 2) Shirts using 5 yards of materials for each of the shirts. The total amount of materials used is thus 5(m + 2) which equals (5m + 10) yards

The total amount of cloth used altogether is thus 2m + (5m + 10) = (7m + 10) yards of cloth
