Answer:
97.96 cm
596.14 cm²
Step-by-step explanation:
sides become:
- 30 cm ⇒ 16 cm
- 25 cm ⇒ 11 cm
and added corners:
- 4*2πr/4= 2πr = 2*3.14*7 cm= 43.96 cm
then perimeter is:
- P= 2*16+2*11+43.96= 97.96 cm
the area left is:
- A= 30*25- 4*1/4*3.14*7²= 596.14 cm²
Answer:
18
Step-by-step explanation:
$14+$5.25=$19.25
$19.25 x 18 = $346.5
Answer:
the answer would be 222/23
What are the the numbers?
Lets look a pyramid numbers
we have
1st=1
2nd=2
3rd=6
we notice that we jsut add the previous number on
so 1st=1
2nd=1+1
3rd=1+2+3
4th=1+2+3+4
so therefor to get from 100th to 101th, just add 101
