Question

What is the approximate perimeter of the composite figure shown? Use three point one four for pi.

A right triangle has a base of 6 miles, a height of 6 miles, and a third side of 9 miles. A semi-circle is attached to the third side such that the length of the diameter is equal to the length of the third side.

twenty-six point one three miles

forty point two six miles

forty-three point seven nine miles

fifty-eight point seven nine miles

Answer 1

@ganeshie8 @dg2

Answer 2

same to find the area of triangle ?
area of triangle=1/2*base*height
then diameter=9 so r=9/2

Answer 3

area of semicircle =pi*r^2/2
total area=area of triangle+AREA of semicircle

Answer 4

can u do that?

Answer 5

No.

Answer 6

Wait I got this.

Answer 7

What's the radius!

Answer 8

nvm.

Answer 9

radius=9/2

Answer 10

28.26+14.3=42.56

Answer 11

Hmm did I do anything wrong @dg2 ?

Answer 12

18 =area of triangle

Answer 13

3) would be correctbut small difference i got

Answer 14

31.79= area of semicircle

Answer 15

so i got 49.79

Answer 16

check ur calculation

Answer 17

So the answer should be c?
