Answer: D. 61 in²
Step-by-step explanation:
This problem is asking for us to solve the area of the given circle. We will use the formula and solve.
<em> Please note that the formula asks for the </em><em>radius </em><em>and 9 in is the </em><em>diameter</em><em>. Since the radius is half the </em><em>diameter</em><em>, we will divide 9 in by 2 for a radius of 4.5 in.</em>
<em />
A = πr²
A = π(4.5 in)²
A ≈ 63.62 in²
The closest option they give to solve this problem is D. 61 in²
About 61 in² of pie crust is needed to cover the top of the pie.
The answer for the exercise shown above is the second option, the option B, which is: B. In step 3, the addition property of equality was applied incorrectly.
The explanation is:
To solve this problem you must apply the proccedure shown below:. You have the followinwg equation:
<span>
4(m-3)+5(m+2)=m+9
Let's review the steps:
4m-12+5m+10=m+9 (step 1)
9m-2=m+9 (step 2)
8m =7 (step 3) (There is a mistake, because: 9m-m=9+2</span>⇒8m=11)
<span> m=11/8 This should be the step 4</span>
Answer:
2x-2=8
Step-by-step explanation:
2x-2=8
2x=8+2
2×=10
2×÷2×=10÷2
×=5
