What is the volume of a hemisphere with a radius of 3 cm, rounded to the nearest tenth of a cubic centimeter?

Kaylis [27]

Formula: V = (2/3) π r 3.

Radius is 3cm.

So, now we can plug it in to solve for the volume.

V = (2/3) π 3^3

First, let's multiply 3^3.

3^3 = 27

Then, 27 x π = 84.82

After, multiply by 2/3.

84.82 x 2/3 = 56.55

Lastly, round 56.55 to the nearest tenth of a cubic centimeter.

56.55 = 56.6

Therefore the volume of a hemisphere with a radius of 3cm is 56.6cm^3.

The diagram shows a sketch of John's yard. He wants to plant grass, so he must calculate the area of the yard. The distance from

Arturiano [62]

The area of the yard is 50,600 square feet.

Option: C.

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

The given information forms a trapezoid.

The AB is the upper base (a) and its length is 200 feet.

The CD is the lower base (b) and its length is 260 feet.

A straight line distance from AB and CD is the height (h) and its measures as 220 feet.

The area of trapezoid A= $\frac{a+b}{2} (h)$ .

A= $\frac{200+260}{2} (220)$ .

= $\frac{460}{2}(220)$ .

=230(220).

=50600 $ft^2.$

Thus the area of John's yard is 50,600 square feet.

Michael Perez deposited a total of $2000 with two savings institutions. Bank A pays interest at the rate of 6%/year, whereas Ban

Whitepunk [10]

Answer: He invested $1200 in bank A and $800 in bank B.

Step-by-step explanation:

Let x represent the amount deposited in bank A.

Let y represent the amount deposited in bank B

Michael Perez deposited a total of $2000 with two savings institutions. This means that

x + y = 2000

The formula for determining simple interest is expressed as

I = PRT/100

Where

I represents interest paid on the loan.

P represents the principal or amount taken as loan

R represents interest rate

T represents the duration of the loan in years.

Considering the amount invested in bank A,

P = x

R = 6%

T = 1 year

I = (x × 6 × 1)/100 = 0.06x

Considering the amount invested in bank B,

P = y

R = 8%

T = 1 year

I = (y × 8 × 1)/100 = 0.08y

If Michael earned a total of $136 in interest during a single year, it means that

0.06x + 0.08y = 136 - - - - - - - - - - -1

Substituting x = 2000 - y into equation 1, it becomes

0.06(2000 - y) + 0.08y = 136

120 - 0.06y + 0.08y = 136

- 0.06y + 0.08y = 136 - 120

0.02y = 16

y = 16/0.02 = 800

x = 2000 - y = 2000 - 800

x = 1200
