Answer:
(a) C=88pi
A=1936pi
(b) Area
(c) Circumference
Step-by-step explanation:
Circumference formula = 2r(pi)
Area formula = pi(r^2)
Circumference = 2(44)(pi) = 88pi
Area = pi(44^2) = 1936pi
When something is paved it is the <u>whole area</u> not just the border so AREA
The chain will <u>surround</u> the place not fill it up so CIRCUMFERENCE
The scale model for this room would be 27 x 20 inches.
Answer:
Length = 367.5 m.
Breadth = 157.5 m.
Step-by-step explanation:
The ratio is 7:3 .
There are 7 + 3 = 10 'parts' in the ratio.
So we work out the multiplier which is 525 / 10 = 52.5
Length = 7 * multiplier
= 7 * 52.5
= 367.5
Breadth = 3 * multiplier
= 3 * 52.5
= 157.5.
Brad sent 11,472 more than leo.
to solve-
5,736 x 3 = 17,208
17,208 - 5,736 = 11,472
