A team in science class placed a chalk mark on the side of a wheel and rolled the wheel in a straight line until the chalk mark

natita [175]

The amount of distance the wheel rolled is the circumference of that wheel. So we know the circumferenece of the wheel is 35cm; this is important because the formula for finding circumference is $2 \pi r = C$ . We can solve this for radius.

$2 \pi r = 35$

Divide by 2.
$\pi r = 17.5$

Divide by $\pi$
$r = 5.57$

So we now know the radius of the wheel is 5.57. We can then use this knowledge to find the area of the wheel. The formula for area is $\pi r^2 = A$

$\pi 5.57^2 = A$

Square 5.57.
$\pi 31.02 = A$

Multiply by $\pi$
$97.47 = A$

This means the answer is the last one in the list given.

3. If the sum of (3+6i) and (4+pi) is (7+81), then what is the value of p?

Aliun [14]

Answer:

p=2

Step-by-step explanation:

(3+6i) and (4+pi) is (7+8i)

3+4 = 7

6i+pi = 8i

Subtract 6i from each side

pi = 8i-6i

pi = 2i

That means p = 2

If I earn 3% simple interest for 10 years on $500, I will earn:

valina [46]

Answer:

$150

Step-by-step explanation:

Simple interest for any principal amount p , rate of interest r and time t is given by

Simple interest = (p*r*t)/100

_________________________________

Given

p =$500

r = 3%

t = 10 years

Therefore SI = $500*3*10/100 = $150.

$150 is earned in 10 years at 3% simple interest on $500.
