Answer:
25
Step-by-step explanation:
p=1÷4pir+2r
1÷4×22÷7×7+2(7)
=11cm+14cm
=25
3.5π cm²
let P represent the perimeter of a circle with radius 7
P = 2×π×r
= 2×π×7
= 14π
the perimeter of a quarter-circle with radius 7 = P÷4
= 14π÷4
= 3.5π
7.1, 7.2, 7.3, 7.4, 7.5, 7.6, 7.7, 7.8, and 7.9
There is no whole number, but there are decimals that fall in between 7 and 8.
