The total surface area of the toy would be = 46.24m².
How to calculate the total surface area of the given toy?
To calculate the total surface area of the given toy, the following steps should be taken as follows:
Given;
∠C = 90°
AC = BC = X
AB² = AC²+BC²
AB² = x²+x²
2x² = (2√2)²
2 x² = 8
x² = 4
X = 2
r = d/2 = 2√2/2 = √2m
Slant height of conical portion = BC = 2m
Total surface area of toy =
2πrh + πrl+ πr²
= 2(3.14)(√2)(3.5)+(3.14)(√2)(2)+(3.14)(√2)²
= 31.08+8.88+6.28
= 46.24 m²
