Answer:
the dimensions of the rectangle are 34cm and 15cm
Step-by-step explanation:
proof:
p= (2 × 34) + (2 × 15)
=68 + 30
= 98
hope this helps!!
i think the answer is y= -2x + 9/4
Answer:
87.92 mm²
Step-by-step explanation:
Given:
- Radius of circular base: 2 millimeters
- Height of cylinder: 5 millimeters
<u>It should be noted:</u>
- Surface area of cylinder: 2πrh + 2πr² (R = Radius; H = Height)
When the measures are substituted, we get the following expression:
Multiply the constants and substitute π as 3.14.
- ⇒ 20π + 2π(4)
- ⇒ 20π + 8π
- ⇒ 20(3.14) + 8(3.14)
Finally, simplify the expression to determine the surface area.
- ⇒ 20(3.14) + 8(3.14)
- ⇒ 62.8 + 25.12
- ⇒ 87.92 mm²
Area of shaded portion = area of circle 1 - circle 2
Pi r*2 - pi R*2 =
Pi (r*2 -R *2 ) = 9*2 - 5*2 = (pi)81- 25= 56 x 3 = 168
Answer:
D. 1000 meters
Step-by-step explanation:
(39370 in)/(39.37 in/m) = (39.37×1000)/(39.37) m = 1000 m
