Circumference = 2 x pi x radius
27 in = 2 x 3.14 x radius
Solve for the radius
Answer:
question 21 is x= 30
Step-by-step explanation:
when you multiply 7 by 5 you get 35 which is on the bottom side. So, to get x you multipy 6 and 5 and that equals 30.

Answer:
20079.05 cm^2,
Step-by-step explanation:
Surface area of the box without the lid
= 90*42 + 2(90*34) + 2(42*34) = 12756.
Now find Surface area of the half cylinder:
The diameter of the 2 half circles = 42 so the radius = 21.
The area of the lid
= 2 + 1/2 π (21)^2 + π r * 90
= 7323,052
Total = 20079.052
