Answer:
SA. = 62.8 +87.92= 150.72
Step-by-step explanation:
surface area of cone without base = pi*r*s = 3.14 * 2* 10 = 62.8
Surface area of cylinder without base = 2*pi*r*h + pi*r*r
= 2* 3.14 * 2 * 6 + 3.14*2*2
= 75.36 + 12.56 = 87.92
SA. = 62.8 +87.92= 150.72
Answer:
Trevon scored -8.
Beth's score was 3/4 of trever's score = -8 *3/4 = -6
leah's score was 1/4 of beth's score. = -6 *1/4 = -1.5
Leah's score was -1.5
The last one would be incorrect. We are looking for PART of whatever N is. Multiply by the whole number 25 is definitely not what we want to do.
Hope I helped!
-7 and positive 6. if you multiply a negative by a positive it will always be a negative.
