Answer:
245 cm²
Step-by-step explanation:
The surface area of a cone is given by ...
SA = πr(r +s) . . . . where r is the radius, and s is the slant height
Filling in the given values, we have ...
SA = (3.14)(3 cm)(3 cm +23 cm) = (3.14)(3)(26) cm² ≈ 245 cm²
The surface area of the cone is about 245 cm².
Answer:
52
Step-by-step explanation:
<u>Spinner A</u>
- Probability of red = 0.5,
- Probability of blue = 0.5
<u>Spinner B</u>
- Probability of red = 0.6,
- Probability of blue = 0.4
<u>Probability of both A and B land on red: </u>
<u>Number of attempts to get outcome of 84 red on both spinners is:</u>
<u>Probability of both spinners land on blue:</u>
<u>Estimated number of both spinners land on blue:</u>
