Answer:
-7/2 or -3.5
Step-by-step explanation:
h = 20
= h = 35 = h = 70 (2h) (2h)
19h = 35h = 70(2h)(2h)
16h = 70(2h)(2h)
-70 = 20h
-7/2 = h
-3.5 = h
The answer is 248. Working out is in the picture.
Answer:
132
Step-by-step explanation:
Find Radius (r)
42/2 = 21
Plug 21 into Circumference Equation
2πr (In this case, π is 22/7)
Simplify
42 (22/7)
<u>132</u>
Split it into 7 triangles. Half-base of each is 2 so the distance of center to the midpoint of the base is (Pythagoras) square root of (4.62 - 22) = 4.162 triangle is this times 2, and with 7 triangles multiply also by 7 to get an approximate area of 58 sq in.
