3 feet is also 2 ft and 12 inches

2' 12" - 9 " = 2' 3"

Answer: $1\frac{1}{4}\ cups$ is needed for 5 servings.

Step-by-step explanation:

Since we have given that

Hemal wanted to make desert for her family for which they made the recipe,

For 8 servings , the number of cups of flour is needed = 2

We will use "Unitary Method" ,

For 1 serving, the number of cups of flour is needed is given by

$\frac{2}{8}=\frac{1}{4}$

For 5 servings, the number of cups of flour is needed is given by

$\frac{1}{4}\times 5=\frac{5}{4}=1\frac{1}{4}\ cups$

Hence, $1\frac{1}{4}\ cups$ is needed for 5 servings.

What is the area of the circle if XY = 5.4 mm?

Semenov [28]

The correct answer would be 22.9^2 mm.

Since area of a circle is 'A = piR^2'.

We don't have the radius (from the middle out) but we do have the diameter (from one point to the other). We can divide this by 2 to find the radius.

5.4/2 = 2.7.

The radius is 2.7.
A = 3.14(2.7^2)
A = 22.8
