Answer:
Answer to question 8 is : Area =1017.88 and Circumference =113.1
Answer to question 9 is: Area =490.87 and Circumference =78.54
Step-by-step explanation:
8. i just did πr2for area and for circumference i did 2πr which is just the equation to find each
9.i found that half of the diameter is 12.5 so i did πr2 to find the Area i filled in the radius and pai and 2πr for circumference filled in the pai and radius
oh also round it if u want
plz give me brainliest and rate it that u and goodluck

Step-by-step explanation:
im sorry if im wrong
The circumference would also be doubled. The formula to find circumference is 2π r; since radius is just the diameter divided by two, if you double it the radius also doubles. All in all, this doubles the circumference. For example, if the diameter was 10, the radius would be 5. Circumference for this circle would equal 31.4. Now, if you were to double the diameter to equal 20, thus making the radius 10, the circumference would be 62.8.
