Answer:

10.21 feet.

Step-by-step explanation:

circumference of circle with diameter d is given by \pi d

where r is the radius of the circle.

_____________________________

given

diameter = 6 1/2 = 13/2 feet

\thus, circumference of circle is calculated as following

circumference = \pi *13/2 = 22/7 * 13/2\\circumference = 11*13/7*2 = 143/14 = 10.21

Thus, circumference of given circle is 10.21 feet.

Answer:

63%

Step-by-step explanation:

<em>From the question, we aim to find the percent increase in the tuition</em>

Given data

initial cost= $99 per credit hour

Final cost=  $268 per credit hour

% increase= (Final - initial )/initial *100

substitute

% increase= (268- 99 )/268 *100

% increase= 169 /268 *100

% increase= 0.630*100

% increase= 63%

Hence the increase in the tuition from 1990 to 2003 is 63%

Bond [772]

Answer:

1: 3×2

2: y^6

Step-by-step explanation:

1:

Multiply the numbers: y(^3^*^2)

3*2 = 6

Write it without exponents:

y * y * y * y *y *y so 6y.

2:

(y^3)^2

Apply exponent rule : (a^b)^c=a^b^c, assuming a\geq 0

(y^3)^2=y^3^*^2

=y^3^*^2

Multiply the numbers: 3 * 2 = 6

= y^6

Hope I helped! If so, may I get Brainliest and a Thanks?

Thank you, have a good one! =)
