Answer:

8 =r

Step-by-step explanation:

The circumference of a circle is given by

C = 2 * pi *r

50.24 = 2 * pi * r

Using 3.14 as pi

50.24 = 2 * 3.14 * r

50.24 = 6.28 r

Divide by 6.28r

50.24/6.28 = 6.28r/6.28

8 =r

Answer:

The radius of the circle is:

8 units.

Step-by-step explanation:

We are given the circumference of a circle as:

Circumference=2πr

We know that:

Circumference of a circle of radius ''r'' units is given by:

$Circumference=2\pi r$

Hence, we have:

$50.24=2\times 3.14\times r\\\\\\r=\dfrac{50.24}{2\times 3.14}\\\\r=8$

Hence, the radius of the circle is:

8 units.

10. Daniels goes to the shopping center. He has a bank account with a

Savatey [412]

Answer:

-$36

Step-by-step explanation:

Daniel has a starting balance of $259, so anything he spends will be deducted by this amount. To find out how much he spent, we need to add up everything he bought.

He spent $45 + $150 + $100, adding to a grad total of $295.

To find out how much money Daniel has left, we need to subtract his purchases from his funds. This would be $259 - $295. This leaves you with a final answer of -$36 in Daniel's bank account.

A triangle has side lengths of (7x-4)(7x−4) centimeters, (x+3)(x+3) centimeters, and (3y+2)(3y+2) centimeters. Which expression

Papessa [141]

Answer:

This assumes that the question was meant to read:

"A triangle has side lengths of (7x−4) centimeters, (x+3) centimeters, and (3x+2) centimeters." And not "A triangle has side lengths of (7x-4)(7x−4) centimeters, (x+3)(x+3) centimeters, and (3y+2)(3y+2) centimeters."

If the revision is correct, the perimeter is 11x + 1 cm

=============================================

If the question was correctly written, then answer is:

50x^2 - 50x + 9y^2 + 12 y + 29

===============

Step-by-step explanation:

(7x-4) cm

+ (x+3) cm

+ (3x+2) cm

11x + 1 cm

If the question was correctly written as is, then:

(7x-4)(7x−4) = 49x^2 - 56x + 16

+(x+3)(x+3) = + x^2 + 6x + 9

+(3y+2)(3y+2) = +9y^2 + 12 y + 4

50x^2 - 50x + 9y^2 + 12 y + 29 cm
