Answer:

1. 78.5

2. 43.96

Step-by-step explanation:

well since

\frac{diameter}{2} = radius

the radius is 5 meters

the area of a circle is

A = \pi r^2\\\\A = \pi (5)^2\\\\A = 25\pi\\\\A \approx 78.5

the circumference of a circle is given by

C = 2\pi r\\\\C = 2\pi (7)\\\\C = 14\pi\\\\C \approx 43.98

guess is close enough to 43.96

Answer:

D

Step-by-step explanation:

Area = pi r^2

d = 10

r = d/2

r = 5

Area = 3.14 * 5^2

Area = 3.14 * 25

Area = 78.5

<u>Geometry:</u>

  • Volume of a Rectangular Prism: V = lwh

Step-by-step explanation:

<u>Step 1: Define</u>

l = 4 cm

w = 6 cm

h = 14 cm

<u>Step 2: Solve for </u><em><u>V</u></em>

  1. Substitute:                    V = (4 cm)(6 cm)(14 cm)
  2. Multiply:                        V = (24 cm²)(14 cm)
  3. Multiply:                        V = 336 cm³

A recipe calls for 1 1/4 cups of flour, 3/4 cup of white sugar, and 1/3 cup of brown sugar. The recipe makes 4 servings. How man
sleet_krkn [62]

Answer:

Cups of flour 5/16

Cups of sugar 3/16

5/8 more cups of flour we need for 6 servings

Step-by-step explanation:

Cups of flour

We need to divide the total of flour (1 1/4) in the total of servings (4)

=(1 1/4)/4

=5/16 cups of flour for servings

Cups of sugar

We need to divide the total of sugar (3/4) in the total of servings (4)

=(3/4)/4

=3/16 cups of sugar for servings

If the recipe is for 6 servings

You need to add more flour and sugar to complete 6 servings

1 1/4 flour=4 servings

x flour=6 servings

(1 1/4 flour*6 serving)/4 servings=x flour

x flour= 15/8 cups of flour

The difference

First 1 1/4 cups

Then 1 7/8

More cups of flour=5/8
