If it's not 6 cubic feet (because by the wording the answer is given).

If one dimension of the amount of soil they remove is 6, then you have to do 6*6*6= 216

If the total amount of soil removed is 6 cubic feet, then the dimensions of the cube would be $\sqrt[3]{6}$

What is the area of the sector with a central angle of 49° and a radius of 11 cm? Use 3.14 for pi and round your final answer to

olga_2 [115]

Answer:

$\boxed{\text{51.71 cm}^{2}}$

Step-by-step explanation:

If the angle θ is in radians, the formula for the area (A) of a sector of a circle is

A = ½r²θ

If θ is in degrees

$A = \dfrac{1}{2}r^{2}\theta \times \dfrac{\pi \text{ rad}}{180^{\circ}}= \pi r^{2}\times\dfrac{\theta }{360}$

Data:

θ = 49°

r = 11 cm

Calculation:

$\begin{array}{rcl}A& = &3.14\times 11^{2}\times\dfrac{49}{360}\\\\ & = &3.14 \times 121 \times 0.1361\\ & = & \mathbf{51.71}\\\end{array}\\\text{The area of the sector is }\boxed{\textbf{51.71 cm}^{2}}$

Paige used 1 1/2 cups of flour and 1/4 of butter to make 12 muffins. How much flour and butter would Paige need for 18 muffins?

maks197457 [2]

Answer:

3/4 cup

Step-by-step explanation:

12 divided by 2 is 6

18 - 12 = 6

we are going to need half of 1 1/2 cup of flour

1 cup = 1/2

1/2 cup = 1/4

1/2 and 1/4 cup = 3/4 cup
