Perimeter and Circumference! Only 5 questions

Mathematics
2 answers:
Anton [14]3 years ago
7 0

Answer:

1. 7.5 m

2. 14π or 43.96 cm

3. 20 cm

4. 5π or 15.7 m

5. 24 m

Step-by-step explanation:

1. You do base×height×1/2. So in this case, it is 5×7×1/2. 5×7 is 35, and that times 1/2 is 17.5 m.

2. To find the circumference is just the radius×2×3.14, or pi. So since the radius is 7, I do 7×2, which is 14, and the answer is 14π, or 14×3.14, which is 43.96 cm.

3. The perimeter for a square is just the side length multiplied by 4, in  this case it is 5×4 which is just 20 cm.

4. To find the circumference with the diameter is just diameter×pi, so it is 5π, or 5×3.14 which is 15.7 m.

5. I added all the sides, the unknown side is just 5+1, and the shorter side is 2, so I did 5+3+6+2+1+3+2+2 and got 24 m.

Hope this helps! If you are still confused, please comment!
