The radius of a cone is 3 mm and the height is 21.3 mm. What is the volume of the cone? Use 3.14 for π. Round to the nearest tenth, if needed. A) 200.6 mm3
B) 66.9 mm3
C) 200.65 mm3
D) 602 mm3

Answers

Answer 1
Answer: V = 1/3 * (pi) * r^2 * h
V = 1/3 * 3.14 * 3^2 * 21.3
V = 1/3 * 3.14 * 9 * 21.3
V = 1/3(601.938)
V = 601.938/3
V = 200.646 rounds to 200.6 mm^3

The amount of interest earned from a savings account was $580. What was the interest rate if $1432 was deposited 6 years before

Answers

Answer:


Step-by-step explanation:

Solving our equation

r = 580 / ( 1432 × 6 ) = 0.06750466

r = 0.06750466

converting r decimal to a percentage

R = 0.06750466 * 100 = 6.7505%/year

The interest rate required to

accumulate simple interest of $ 580.00

from a principal of $ 1,432.00

over 6 years is 6.7505% per year.

A football field is 100 yards in length. How many inches long is a football field?

Answers

The football field is 3600 inches long

From the question,

We are to determine how many inches long the football field is

From the given information,

The football filed is 100 yards in length.

To determine the length of the football field in inches, we will convert 100 yards to inches

(NOTE: 1 yard = 36 inches)

Since 1 yard = 36 inches

Then,

100 yards = 36 × 100 inches

100 yards = 3600 inches

Hence, the football field is 3600 inches long

26.35 rounded to the nearest hundred

Answers

Answer:

Nearest hundred: 0

Nearest hundredth: 26.35

Step-by-step explanation:

The hundred place value is three numbers to the left of the dot.

The two hundreds that are nearest to 26.35 are 0 and 100. To decide if you should round up (to 100) or round down (to 0), use the place value that is to the right of the hundred place: the number you are using is 2.

The rule for rounding:

Round up if the place value is 5 or more

Round down if the place value is 4 or less

Since 2 is "4 or less", round down to 0.

Since 26.35 is closer to 0 than 100:

26.35 => 0 when rounded to the nearest hundred

In case you meant hundredth:

The nearest hundredth means two decimal places, or two numbers right of the dot.

The number 26.35 already has two decimal places, so rounded to the nearest hundredth is still 26.35.

26.35 => 26.35

What is the arc length if θ = 2 pi over 7 and the radius is 3 cm?

Answers

Arc length = θ/2pi * 2pi * r = θ * r = 2pi/7 * 3 = 6pi/7 = 2.69 cm

Answer:

Length of the arc will be 2.69 cm.

Step-by-step explanation:

We have to calculate the length of an arc if θ = and radius of arc is 3 cm.

As we know length of an arc = r × θ

By putting the values of angle θ and radius of arc r in the formula

m (arc) =   × 3

           =  

           =  

           = 2.69 cm

Therefore, length of the arc will be 2.69 cm.
