Question

Will give brainliest!! Part of me thinks the answer is D but I just want to double check.

Answer 1

Answer: C) 6.0025

Step-by-step explanation:

The equation for the area of a circle requires the radius, you put in the full diameter. Just divide 4.9 by 2, which gives you 2.45. 2.45 squared is equal to 6.0025 and then slap your pi on to the end of it.

Answer 2

Answer:

$6.0025\pi \: {m}^{2}$

Step-by-step explanation:

The formula for the area of a circle:

$\pi \times {r}^{2}$

We are given the diameter of the circle, which is two times its radius. To find the radius, we divide the diameter by 2.

4.9 ÷ 2 = 2.45 m^2.

Now we need to square the radius:

${2.45}^{2} = 6.0025$

So, the area in terms of pi would be

$\pi \ \times {6.0025}^{2} \: {m}^{2}$

Or

$6.0025 \times \pi \: {m}^{2}$

Hope this helps!
