The shape shown is a right-angled triangle together with two quarter-circles of radius r сm.
a Find the formulae for the area A and the perimeter
P of the shape.
b Find the area and perimeter when r = 3 cm.
c Find r when A = 12 cm?.​

109 trust me

step-by-step explanation:

for this case we have that by definition, the volume of a cylinder is given by:

where:

r: it's the radio

h: it's the height

we have as data that:

substituting:

so, the cylinder volume is

option d

differentiate (x^14(x^-2)^4with respect to the variable

the parentheses don't balance in your input.

differentiate 0 with respect to

the final answer is

0

hope this
