Answer 1

24.997

Explanation:

its actually really hard for me to explain im sorry i only know the answer-

Answer 2

Perimeter = 12.5 cm

Explanation:

Perimeter of quarter cirlce:

d = 7 cm

`\sf \boxed{\text{Circumference of quarter circle =$(1)/(4) \pi d$}}`

`\sf = (1)/(4)*(22)/(7)*7\\\\ =(11)/(2)\\\\ = 5.5 \ cm`

Perimeter = radius + radius + circumference of quarter circle

= diameter + circumference of the quarter circle.

= 7 + 5.5

= 12.5 cm
