To solve:
Take 2 and multiply it by 2.6 (because 2 and six-tenths times a number is
and that converts to 2.6)
If you multiply it, you get 5.2. And after that, you add 5 to that and you get 10.2. So the answer to this question will be B.
Answer:
48
Step-by-step explanation:
56-8=48
Step-by-step explanation:
diameterfor first minute :
Circumference = 25.12
2πr = 25.12
22/7 × r = 25.12/2
r = 12.56 × 7 /22
r = 87.92/22
r = 3.99 mm ( approx. )
diameter = 2r = 2 × 3.99 = 7.98 mm
diameter for second minute =
circumference = 75.63
2πr = 75.63
πr = 75.63/2
r = 37.815 × 7/22
r = 264.705/22
r = 12.032 mm
diameter = 2r = 24.064 mm
<em><u>COMPARISON</u></em><em><u> </u></em>: 24.064/7.98

Answer:
Step-by-step explanation:
a) V= A*h V=40*8=320
b) V=800 and h=20
A=V/h=800/20=40
Answer:
<u>Solving it mentally</u> :-
It says 25% × 44. When we have a percent, change it to decimal and solve which would be easy to do it mentally.
25% = 0.25
0.25 × 44 = 11 *Answer is bolded.*
<u>Solving it on paper</u> :-
I have attached a picture of me doing it on paper.
Hope this helps, thank you :) !!
