Answer:
Solution given;
angle =270°
radius [r]=8cm
we have
length of arc =270°/360°×2×π*r
=270°/360°×2×3.14*8=37.68cm
<u>length of the </u><u>arc</u><u> </u><u>is</u><u> </u><u>37.68</u><u>cm</u><u>.</u>
Answer:
B) 65 sq in
Step-by-step explanation:
SA = area of base + 1/2(perimeter of base)(slant height)
= 5² + 1/2(20)(4)
= 25 + 40

Answer:
25deg 55deg 100deg
Step-by-step explanation:
There are 180deg in a triangle. We know one angle is 30deg more and the other 75deg more than the smallest angle so we subtract that from 180.
180-75-30 = 75
We divide 75deg by 3 because there are 3 angles.
75/3 = 25
So we know the smallest angle is 25deg. We have to add 30deg to one angle and 75 to the other in oder to find the remaining angles.
25+30 = 55deg
25+75 = 100deg
So the angles are 25deg, 55deg, and 100deg.
