A ball has a radius of 8 cm. What is the volume of the ball? Use 3.14 for pie Round your answer to the nearest tenth of a cubic
AveGali [126]

The volume of the ball is 33.5 cubic centimeter.

<u>Step-by-step explanation:</u>

It is given that, a ball has a radius of 8 cm.

We know that, the ball is in shape of the sphere.

The question is asked to find the volume of the ball.

To find the volume of the ball, you need to use the formula for volume of the sphere.

Volume of the sphere = (4/3)πr³

where,

  • π has the default value of 3.14
  • r is the radius of the ball.

Volume of the ball = (4/3)× 3.14× 8

⇒ 33.49

⇒ 33.5 (rounded to the nearest tenth)

⇒ 33.5 cubic centimeter.

∴ The volume of the ball is 33.5 cubic centimeter.

It is 170 miles from Bruce's house to the city where his brother lives. On his last trip to visit his brother, he drove for 2 ho
Rom4ik [11]

Speed of Bruce for the rest of the trip is 30 miles/hour.

Step-by-step explanation:

  • Step 1: Total distance = 170 miles. In the trip Bruce's speed = 55 miles/hour. So, in 1 hour, distance covered = 55 miles. Find distance covered in 2 hours and the distance of the last part.

Distance covered in 2 hours = 2 × 55 = 110 miles

Remaining part of the trip = 170 - 110 = 60 miles

  • Step 2: Find the speed of Bruce in the remaining part of the trip when time = 2 hours and distance = 60 miles.

Speed = Distance/Time = 60/2 = 30 miles/hour

a family buys a new home for $212,500 and pays a 20% down payment ($42,500). if the mortgage is for 15 years at 5.75% interest w
diamong [38]

Answer:

Their monthly house payment is of $2,184.65.

Step-by-step explanation:

Compound interest:

The compound interest formula is given by:

A(t) = P(1 + \frac{r}{n})^{nt}

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.

A family buys a new home for $212,500 and pays a 20% down payment ($42,500).

This means that the loan is of 212,500 - 42,500 = $170,000, that is, P = 170,000

Value of the loan in 15 years:

15 years means that t = 15

5.75% interest means that r = 0.0575

Compounded yearly, so n = 1

Then

A(t) = P(1 + \frac{r}{n})^{nt}

A(15) = 170000(1 + \frac{0.0575}{1})^{15}

A(15) = 393237

Monthly payment:

Total of $393,237 in 15*12 months. So

M = \frac{393237}{15*12} = 2184.65

Their monthly house payment is of $2,184.65.
