Answer: 907.92 ft²

Step-by-step explanation:

1. To solve this problem you must apply the formula for calculate the area of a circle, which is shown below:

A=r^{2}\pi

Where r is the radius of the circle.

2. You know the radius of the circle B, therefore, when you susbtitute it into the formula, you obtain that the area of the circle B is:

A_B=(17ft)^{2}\pi=907.92ft^{2}

A 10-acre parcel was sold for $3.50 per square foot. What was the total selling price for the parcel
disa [49]

Answer:

The total selling price for the parcel is 1,524,600 dollars.

Step-by-step explanation:

We are given that 10 acre parcel was sold for $3.50.

First we need to figure out how many square foot is in 10 acres.

when we convert 10 acres we get 435600 square feet.

Since we know that parcel was sold for $3.50 per square foot we simply multiply 435600 by 3.5 = 1,524,600

Help please!!!!!! 12-13 8th grade math!!!
marin [14]

Answer:

12.

m∠ACB = 180° - 58° - 78° = 44°

m∠DCE = 180° - 85° - 60° = 35°

m∠BCD = 180° - 44° - 35° = 101°

13.

Base on the picture, we know that:

x° + 2x° + 3x° = 180°

6x°                 = 180°

x°                   =  180° ÷ 6 = 30°

=> m∠K = 2x° = 2 × 30° = 60°

=> m∠L = 3x° = 3 × 30° = 90°

=> m∠KML = x° = 30°

m∠LMN =  60° + 90° = 150°

What is the approximate volume of one refraction cup? What’s its formula ?
Marizza181 [45]

Answer:

Volume = 0.1696 L

The formula is Area of base of refraction cup × Depth of the refraction cup

Step-by-step explanation:

The dimensions of a refraction cup are;

Diameter = 120 mm

Depth = 30 mm

Therefore, volume of the refraction cup = Area of base × Depth

Volume of the refraction cup = (π×120²/4)/2 × 30 = 169646.003 mm³

1 L = 1000000 mm³

Therefore, 169646.003 mm³ = 169646.003/1000000 m³ = 0.1696 L

The formula is Area of base of refraction cup × Depth of the refraction cup.
