Answer:
Step-by-step explanation:
Each circle is pi*r*r (pi r squared)
So 2*pi*r*r
The top of the rectangle if just the circumference of the circle = 2*pi*r
So the area of the rectangle is 2*pi*r*h
So the total area =2*pi*r*r+2*pi*r*h
Use p.e.m.d.a.s.
<span>first multiply 6Q and 8Q = 48Q
then subtract 58Q and 48Q = 10Q

The square has area 8*8=64, the rectangle has area 7*4=28, and the triangle has area 7*6/2=21. Their sum is 64+28+21=113.
Answer:
Acceleration = 3m/s²
Step-by-step explanation:
Here ,
Initial velocity = 30km/h
Final velocity = 0km/h
Time = 10s
Acceleration = ?
We know ,
A = v-u/t
or , A = 0-30/10
or, A = 30/10
A = 3m/s²
Therefore the acceleration is 3m/s²
Answer:
Step-by-step explanation:
if we have a right triangle,
one angle=90
180-90=90
let x be one angle, and y another angle
the other is 2x+30
x+2x+30=90
3x=60
x=20
y=70
