I am pretty sure the answer is d
Answer:
A
Step-by-step explanation:
Area of a circle is pi * radius² so:
1) Area = pi * 5²
= 25pi ≈ 78.54 yd²
2) Area = pi * 7²
= 49pi ≈ 153.94 cm²
Circumference is 2 * pi * radius so:
3) Circumference = 2 * pi * 10
= 20pi ≈ 62.83 mi
4) Circumference = 2 * pi * 3.3
= 6.6pi ≈ 20.73 in
Volume of a rectangular prism is length * width * height
5) Volume = 10 * 3 * 10
= 100 * 3
= 300 yd³
6) Volume = 5 * 7 * 5
= 35 * 5
= 175 in³
Not completely sure on the triangular prisms though. I'm almost certain the formula is 1/2 * height * base 1 * base 2 though
