Answer:
Twice the radius
As with circles, the diameter of a sphere is twice the radius. C = πD or 2πr. As with circles, the circumference of a sphere is equal to π times the diameter. Since the diameter is twice the radius, we can also say that the circumference is twice the radius times π. V = (4/3)πr3
Explanation:
The correct answer is option 3: "Tonight, Shea read a short story, practiced soccer, and chatted with Betsy". Remember that whenever you need to use parallel structures, you have to use <u>the same tense or word pattern</u>. In option 3, you have three verbs. The three of them are in the past simple tense. Option 1, "Last evening, Shea read "The Necklace", study her physics, and to buy her prom dress" is not grammatically correct. That sentence presents different tenses and the verbs are not well conjugated. Therefore, It is not written in proper parallel structure. Option 2, "Yesterday, Shea bought her dress, had completed her calculus problems, and was talking to Bobby" is not grammatically correct either. Although the sentence is stated in the past, the order of the events is not clear and the verbs do not belong to exactly the same tense. To conclude, option 3 is the only sentence written in proper parallel structure.
