1) 136 is the circumference of a circle with what area? we know C=πd.
136=πd
136/π=d
d=43.290 so the radius is half that, or
r=21.645
taking area as our measure of size,
A=πr²
A=π•21.645²
A=1471.855. answer C is closest. difference is in how they and I rounded
2) c, e, and f
Answer:
54
Step-by-step explanation:
x-1=3
2xy=24
3+24=27
27·2=54
1) calculate the volume of the tri prism 2) find area of the base face 3) find the height 4) multiply area of the triangle base time height 5) answer will be in cubic units
