C= 2*pi*r
pi= approx. 3.14
So
The first one with the radius being 18 would be approximately 113.04
BECAUSE 18 * 2 = 36
36*3.14= 113.04
DO THE SAME PROCESS with the other values you were given...
Also if they give you the diameter the formula is C= d*pi
that formula is the same as c=2*pi*r ..... Use either... just remember when they give you the radius.... the radius is half of the diameter... so take the radius times 2 and times that by pi
When it asked for an approximation use 3.14 for pi.
I'm sure you can do the rest by yourself. I hope this helped!
if an hour is able to be split up for payment then it will be 1/10 of an hour
That's easy you just need to listen in school to answer it
Answer:
Answer is 3bu2(DeEZ)=1
Step-by-step explanation:
Answer:
Hello! answer: 39
Step-by-step explanation:
Formula for triangles area: base × height ÷ 2
Formula for squares area: base × height
5 × 3 = 15 15 ÷ 2 = 7.5 since there are 4 triangles that are the exact same I will just multiply by 4 so I have all the triangles so 7.5 × 4 = 30 now the square is just 3 × 3 so... 3× 3 = 9 now we add these up 30 + 9 = 39 therefore the surface area is 39
