Answer:
153m
Step-by-step explanation:
perimeter of an arc = theta/360 × 2πr
P= 17πm
theta = 20°
17πm= 20/360 × 2 × π × r
153πm = πr
r = 153m
You would have 6cm as the width because length times width = area
Answer:
f(4)=14
Step-by-step explanation:
a) u do it by substituting 4 in places where there r 'x'
since this one say f(4) it only can go to the function which says f(x)
f(x)=4x-2
f(4)=4(4)-2, so according to BODMAS rule multiplication comes first rather than subtraction
so, f(4)=16-2=14
f(4)=14
do the others based on this, hope i explained well, if i did, please gimme brainliest :)
