Shaklning tavsifi Shakl to'g'ri to'rtburchak, 2 ta bir xil chorak doira va yarim doiradan hosil qilingan. Uning o'lchamlari quyidagilar: 14 m (to'rtburchakning uzunligi), 7 m (chorak doiralarning radiusi) va 7 m (yarim doiralarning radiusi).

a) Shakining perimetrini toping

Perimetr - shaklning chegarasining uzunligi. To'rtburchakning perimetrini topish uchun, biz uning to'rt tomonining uzunligini hisoblashimiz kerak. To'rtburchakning uzunligi 14 m, chorak doiralarning radiusi 7 m, shuning uchun ularning uzunligi 2 * pi * 7 m = 14 m. Yarim doiralarning radiusi ham 7 m, shuning uchun ularning uzunligi pi * 7 m = 7 m. To'rtburchakning perimetrini topish uchun, biz to'rt tomonining uzunligini yig'ishimiz kerak: 14 m + 14 m + 7 m + 7 m = 42 m.

Chorak doiralarning perimetrini hisoblash Chorak doiralarning perimetrini hisoblash uchun, biz ularning radiusini hisoblashimiz kerak. Chorak doiralarning radiusi 7 m, shuning uchun ularning perimetrini hisoblash uchun biz quyidagilarni hisoblashimiz kerak: 2 * pi * 7 m = 14 m.

Yarim doiralarning perimetrini hisoblash Yarim doiralarning perimetrini hisoblash uchun, biz ularning radiusini hisoblashimiz kerak. Yarim doiralarning radiusi 7 m, shuning uchun ularning perimetrini hisoblash uchun biz quyidagilarni hisoblashimiz kerak: pi * 7 m = 7 m.

Jami perimetr Jami perimetrni hisoblash uchun, biz to'rtburchakning perimetrini, chorak doiralarning perimetrini va yarim doiralarning perimetrini yig'ishimiz kerak: 42 m + 14 m + 7 m = 63 m.

b) Shaklning yuzini toping

Yuz - shaklning ichki maydoni. To'rtburchakning yuzini topish uchun, biz uning to'rt tomonining uzunligini hisoblashimiz kerak. To'rtburchakning uzunligi 14 m, chorak doiralarning radiusi 7 m, shuning uchun ularning uzunligi 2 * pi * 7 m = 14 m. Yarim doiralarning radiusi ham 7 m, shuning uchun ularning uzunligi pi * 7 m = 7 m. To'rtburchakning yuzini topish uchun, biz to'rt tomonining uzunligini yig'ishimiz kerak: 14 m * 14 m = 196 m^2.

Chorak doiralarning yuzini hisoblash Chorak doiralarning yuzini hisoblash uchun, biz ularning radiusini hisoblashimiz kerak. Chorak doiralarning radiusi 7 m, shuning uchun ularning yuzini hisoblash uchun biz quyidagilarni hisoblashimiz kerak: 2 * pi * 7 m^2 = 14 m^2.

Yarim doiralarning yuzini hisoblash Yarim doiralarning yuzini hisoblash uchun, biz ularning radiusini hisoblashimiz kerak. Yarim doiralarning radiusi 7 m, shuning uchun ularning yuzini hisoblash uchun biz quyidagilarni hisoblashimiz kerak: pi * 7 m^2 = 7 m^2.

Jami yuz Jami yuzni hisoblash uchun, biz to'rtburchakning yuzini, chorak doiralarning yuzini va yarim doiralarning yuzini yig'ishimiz kerak: 196 m^2 + 14 m^2 + 7 m^2 = 217 m^2.

Natija Shaklning perimetrini topish uchun, biz to'rtburchakning perimetrini, chorak doiralarning perimetrini va yarim doiralarning perimetrini hisoblashimiz kerak. Jami perimetr 63 m. Shaklning yuzini topish uchun, biz to'rtburchakning yuzini, chorak doiralarning yuzini va yarim doiralarning yuzini hisoblashimiz kerak. Jami yuz 217 m^2.
