To the nearest square meter, what is the curved surface area of the half pipe if it’s 7 m long? the radius is 2.5 m

if x decreases by 4 then y increases by 10

step-by-step explanation:

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
