Answer:

diameter = 8 miles

Step-by-step explanation:

Area of a circle = πr²

πr² = 50.24

3.14*r² = 50.24

r²= $\frac{50.24}{3.14}\\\\$

r² = 16

r² = 4²

r=√4²

r = 4 miles

diameter = 2 *radius = 2*4 = 8 miles

X=24

First you find the third side of the smaller triangle by using the Pythagorean theorem. You find that is it 100. Then you subtract that from 26 squared. After you get that, you square root the answer to get 24

Look at the way that Samuel answered the question above.

Solnce55 [7]

A) Multiplication is done wrong. The + sign with 16 underlined in the term -16m+16=-16 is wrong. it should be -16.

B) After solving $-2(8m+8)=-16$ correctly we get m=0

Step-by-step explanation:

A) Explain his mistake in complete sentences.

Samuel has done the mistake while performing the step:

$-2(8m+8)=-16$

When we multiply -2 with the terms inside the bracket, we apply the rule that if we have one positive sign (+) and one negative sign (-) while multiplying the result would have negative sign(-) i.e,

$-16m-16=-16$

While Samuel has calculated as $-16m+16=-16$

The + sign with 16 underlined in the term -16m+16=-16 is wrong. it should be -16.

B) Explain how to solve the equation correctly

Now, solving the given expression:

$-2(8m+8)=-16\\Multiplying\,\,-2\,\,with\,\,terms\,\,inside\,\,the\,\,bracket.\\-16m-16=-16\\Adding\,\,+16\,\, on\,\, both\,\, sides\\-16m-16+16=-16+16\\-16m=0\\Divide\,\,both\,\,sides\,\,by\,\,-16\\m=0$

So, the value of m is m=0
